1/4th distance is reached at 7:30 and 1/3rd distance is reached at 7:35
Hence (1/3)-(1/4)=1/12 distance will be covered in 5 mins.
If 1/12th of the total distance is covered in 5 mins then, the boy needs 60 mins to cover total distance (i.e., 5*12=60)
1/4th of 60 mins is 15 mins. Hence the boy would have left 15 mins before 7:30
Hence the boy leaves the house at 7:15 and reaches his school at 8:15
