speed = distance / time

distance = 15 × 2 = 30

&

distance = 5 × 8 = 40

40 - 30 = 10

I think it is the answer

Answer:

Let distance between the school and his house = 'x' km.

case 1

speed = 15 km/hr

time taken = x/15 hr

Case 2

Speed = 20 km/hr

Time taken = x/20

According to statement

x/15 - 2/60 = x/20 + 8/60

x/15 - x/20 = (8 + 2)/60

(4x - 3x)/60 = 10/60

x = 10 km.
