Question

a boy going to school by walk at the speed of 10km/hr and reached 15 minutes late and he walk by cycle at the 12km/hour and reached 10 minute early what the distance of school from home

Answer 1

Let the distance between home and school be x.

Calculate time needed to walk to school:

Time = Distance ÷ Speed

Time = x/10

Calculate the time needed to cycle to school:

Time = Distance ÷ Speed

Time = x/12

Find the difference in time:

15 min + 10 min = 25 mins

25 mins = 25/60 = 5/12 hours

Solve x:

x/10- x/12 = 5/12

x/60 = 5/12

12 x = 300

x = 25 km

Answer: The distance is 25 km.
