Riya and Priya complete a 200 metres race in 1 minute 12 seconds and 1 minute 26 seconds respectively. By how many metres will Riya defeat Priya ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 32 metres
Riya's time to complete = 1 min 12 s = 72 seconds
Priya's time to complete = 1 min 26 s = 86 seconds
$Speed=\frac{Distance}{Time}$
$S_R=\frac{200}{72},S_P=\frac{200}{86}$
Distance covered by Priya in 72 seconds = $\frac{200}{86}×72=167.76m$
Distance = $200-167.76≃32m$
