Answer:

Step-by-step explanation:

Given : A student goes to his school from his house at a speed 3 km/hr and return at a speed 2 km/hr . if he takes 5 hours in going and coming.

To find : The distance between his house and school?

Solution :

Let the required distance be x km.

Then,

Time taken on going = x/3

Time taken on coming=x/2

Total time taken = 5 hr

According to question,

x/3+x/2=5

(2x+3x)/6=5

5x=6*5

5x=30

x=6

Therefore, The distance between his house and school is 6 km.
