Calculating the Speed for the Remaining Distance:
To find the speed at which the train must travel the next 90 km in order to achieve an average speed of 60 km per hour for the entire trip, we can use the concept of average speed.
Understanding the Concept of Average Speed:
The average speed for the entire trip can be calculated by taking the total distance traveled and dividing it by the total time taken. In this case, the total distance is 120 km, and the total time taken is the sum of the time taken to travel the first 30 km and the time taken to travel the next 90 km.
Calculating the Time taken for the First 30 km:
Time = Distance/Speed
Time = 30 km / 30 km per hour
Time = 1 hour
Calculating the Time taken for the Entire Trip:
Average Speed = Total Distance / Total Time
60 km per hour = 120 km / (1 hour + Time taken for the next 90 km)
Finding the Speed for the Next 90 km:
To find the speed at which the train must travel the next 90 km, we can rearrange the formula for average speed:
Time taken for the next 90 km = 90 km / Speed for the next 90 km
Substitute the values into the equation and solve for the speed for the next 90 km.
This will give you the speed at which the train must travel the next 90 km in order to achieve an average speed of 60 km per hour for the entire trip.
