Problem Statement:
- Speed of Boat in Still water: 40 Km/hr
- Speed of Stream: 20 Km/hr
- Distance between Point A and Point B: 480 Km
- Boat started traveling downstream from A to B, halfway, it is powered by an Engine, due to which speed of the Boat increased.
- Boat reached Point B and started back to point A with help of the same engine.
- Time taken for the entire journey: 19 hours
- Find the increased speed of the boat with the help of the engine.
Calculating the speed of the boat downstream:
- Speed of Boat downstream = Speed of Boat in still water + Speed of Stream
- Speed of Boat downstream = 40 + 20 = 60 Km/hr
Calculating the speed of the boat upstream:
- Speed of Boat upstream = Speed of Boat in still water - Speed of Stream
- Speed of Boat upstream = 40 - 20 = 20 Km/hr
Let's assume the distance traveled by the boat from Point A to the midway point is 'x' km.
So, the remaining distance from the midway point to Point B will be (480 - x) km.
Let's calculate the time taken by the boat to travel from Point A to the midway point:
- Time taken = Distance / Speed
- Time taken = x / 60
Now, after the boat is powered by the engine, let's assume the speed of the boat increases by 'y' Km/hr.
So, the speed of the boat downstream becomes (40 + y) Km/hr.
Let's calculate the time taken by the boat to travel from the midway point to Point B with the increased speed:
- Time taken = Distance / Speed
- Time taken = (480 - x) / (40 + y)
Total time taken by the boat to travel from Point A to Point B:
- Total time taken = Time taken from Point A to midway point + Time taken from midway point to Point B
- Total time taken = x / 60 + (480 - x) / (40 + y)
Similarly, let's calculate the time taken by the boat to travel from Point B to the midway point:
- Time taken = Distance / Speed
- Time taken = (480 - x) / (40 - y)
Let's calculate the time taken by the boat to travel from the midway point to Point A with the increased speed:
- Time taken = Distance / Speed
- Time taken = x / (40 + y)
Total time taken by the boat to travel from Point B to Point A:
- Total time taken = Time taken from Point B to midway point + Time taken from midway point to Point A
- Total time taken = (480 - x) / (40 - y) + x / (40 + y)
Given, the total time taken by the boat to travel from Point A to Point B is 19 hours.
- Total time taken = 19
- x / 60 + (480 - x) / (40 + y) = 19 - (480 - x) / (40 - y) - x / (40 + y)
Simplifying the above equation:
- x / 60 + (480 - x) / (40 + y) + (480 - x) / (40 - y) + x / (40 + y) = 19
Simplifying further:
- 2
- Speed of Boat in Still water: 40 Km/hr
- Speed of Stream: 20 Km/hr
- Distance between Point A and Point B: 480 Km
- Boat started traveling downstream from A to B, halfway, it is powered by an Engine, due to which speed of the Boat increased.
- Boat reached Point B and started back to point A with help of the same engine.
- Time taken for the entire journey: 19 hours
- Find the increased speed of the boat with the help of the engine.
Calculating the speed of the boat downstream:
- Speed of Boat downstream = Speed of Boat in still water + Speed of Stream
- Speed of Boat downstream = 40 + 20 = 60 Km/hr
Calculating the speed of the boat upstream:
- Speed of Boat upstream = Speed of Boat in still water - Speed of Stream
- Speed of Boat upstream = 40 - 20 = 20 Km/hr
Let's assume the distance traveled by the boat from Point A to the midway point is 'x' km.
So, the remaining distance from the midway point to Point B will be (480 - x) km.
Let's calculate the time taken by the boat to travel from Point A to the midway point:
- Time taken = Distance / Speed
- Time taken = x / 60
Now, after the boat is powered by the engine, let's assume the speed of the boat increases by 'y' Km/hr.
So, the speed of the boat downstream becomes (40 + y) Km/hr.
Let's calculate the time taken by the boat to travel from the midway point to Point B with the increased speed:
- Time taken = Distance / Speed
- Time taken = (480 - x) / (40 + y)
Total time taken by the boat to travel from Point A to Point B:
- Total time taken = Time taken from Point A to midway point + Time taken from midway point to Point B
- Total time taken = x / 60 + (480 - x) / (40 + y)
Similarly, let's calculate the time taken by the boat to travel from Point B to the midway point:
- Time taken = Distance / Speed
- Time taken = (480 - x) / (40 - y)
Let's calculate the time taken by the boat to travel from the midway point to Point A with the increased speed:
- Time taken = Distance / Speed
- Time taken = x / (40 + y)
Total time taken by the boat to travel from Point B to Point A:
- Total time taken = Time taken from Point B to midway point + Time taken from midway point to Point A
- Total time taken = (480 - x) / (40 - y) + x / (40 + y)
Given, the total time taken by the boat to travel from Point A to Point B is 19 hours.
- Total time taken = 19
- x / 60 + (480 - x) / (40 + y) = 19 - (480 - x) / (40 - y) - x / (40 + y)
Simplifying the above equation:
- x / 60 + (480 - x) / (40 + y) + (480 - x) / (40 - y) + x / (40 + y) = 19
Simplifying further:
- 2
