DIRECTIONS: Choose the most appropriate answer.Q. A man travelled from...
Explanation:
To find the distance between points A and B, we need to use the formula:
Distance = Speed x Time
Let's assume the distance between points A and B is 'd' km.
Time taken to travel from A to B:
Given that the man traveled from A to B at a rate of 25 km/h, we can calculate the time taken using the formula:
Time = Distance / Speed
= d / 25
Time taken to walk back from B to A:
Given that the man walked back from B to A at a rate of 4 km/h, we can calculate the time taken using the formula:
Time = Distance / Speed
= d / 4
Total time taken:
The whole journey took 5 hours and 48 minutes, which can be converted to hours as follows:
5 hours + 48 minutes = 5 + 48/60 = 5 + 0.8 = 5.8 hours
According to the given information, the total time taken is 5.8 hours. We can write this as:
Total time = Time taken to travel from A to B + Time taken to walk back from B to A
= d / 25 + d / 4
= (4d + 25d) / 100
= 29d / 100
Since the total time taken is 5.8 hours, we can write:
29d / 100 = 5.8
Solving for 'd':
To find the value of 'd', we can cross multiply and solve the equation:
29d = 5.8 x 100
d = (5.8 x 100) / 29
d = 20
Therefore, the distance between points A and B is 20 km.
So, the correct answer is option 'C' (20 km).
To find the distance between points A and B, we need to use the formula:
Distance = Speed x Time
Let's assume the distance between points A and B is 'd' km.
Time taken to travel from A to B:
Given that the man traveled from A to B at a rate of 25 km/h, we can calculate the time taken using the formula:
Time = Distance / Speed
= d / 25
Time taken to walk back from B to A:
Given that the man walked back from B to A at a rate of 4 km/h, we can calculate the time taken using the formula:
Time = Distance / Speed
= d / 4
Total time taken:
The whole journey took 5 hours and 48 minutes, which can be converted to hours as follows:
5 hours + 48 minutes = 5 + 48/60 = 5 + 0.8 = 5.8 hours
According to the given information, the total time taken is 5.8 hours. We can write this as:
Total time = Time taken to travel from A to B + Time taken to walk back from B to A
= d / 25 + d / 4
= (4d + 25d) / 100
= 29d / 100
Since the total time taken is 5.8 hours, we can write:
29d / 100 = 5.8
Solving for 'd':
To find the value of 'd', we can cross multiply and solve the equation:
29d = 5.8 x 100
d = (5.8 x 100) / 29
d = 20
Therefore, the distance between points A and B is 20 km.
So, the correct answer is option 'C' (20 km).
