Rahul can run 34.4 m in the given time as Amit runs 50 m. By how much distance Rahul is away from Amit at the winning point, in a two km race ?

624 m

The correct answer is Option (4) → 624 m

$\frac{Rahul's\, Speed}{Amit's\,speed}=\frac{34.4}{50}=0.688$

$t_r=\frac{t_A}{0.688}$

Rahul's Distance = $2000×0.688=1376m$

The distance by which Rahul is behind Amit is,

$2000-1376=624m$
