In a 100m race, Jami beats Rony by 4 sec. If Jami allowed Rony to start 16m ahead of him, then Jami and Rony reach the finishing point at the same time. How long does Jami take to run the 100m race?

Correct Answer: 21 sec.
100/Vr - 100/Vj = 4 - - - - (1) 100/Vj = 84/Vr = 21 - - - - (2) solve these 2 equations , Vr = 4   Tj = 100/Vj - - - - > solve from 1st equation , Tj = 21
