Explanation


Explanatory Answer

Let time taken to reach school be T

  • Amit travelled at 4/ 3 of his usual speed, thus he will take ¾ of his usual time to travel same distance.

(T – 2t)/T = ¾ and so T = 8t   ( since time taken was ¾)

Next day let us assume he reached late by x. So,

(T + t + x)/T = 11/8 and so t + x = 3T/8

Since T = 8t, solving above equation we x = 2t
