Question

Raghu goes to college at a speed of 4 kmph and returns at a speed of 3 kmph. If he takes 5.95 hrs in all,

then what is the distance between his home and the college?
​

Answer 1

Answer:

10.2 km

Step-by-step explanation:

Let the distance one way be x km.

Time taken to go college:

Time = Distance ÷ Speed

Time = x/4 hours

Time taken to go home:

Time = Distance ÷ Speed

Time = x/3 hours

The total time is 5.95 hour

x/4 + x/3 = 5.95

3x + 4x = 71.4

7x = 71.4

x = 10.2 km

Answer: The distance between home and college is 10.2 km
