In a 1200 m race, the ratio of the speeds of two contestants Meenal and Nitu is 5:7. If Meenal has a start of 500 m,then Meenal wins by:
Answer & explanation
Correct answer: option 1
Let the speed of Meenal = 5
& speed of Nitu = 7
Distance to be covered by Meenal = 1200 – 500 = 700 m
Time taken by Meenal to cover 700 metres = \(\frac{DIstance}{Speed}\)
= \(\frac{700}{5}\) = 140 minutes
Distance covered by Nitu in 140 minutes = Speed × Time
= 7 × 140 = 980 m
So , Meenal won by = 1200 – 980 = 220 m
