Sukriti and Saloni are athletes. Sukriti covers a distance of 1 km in 5 minutes and 50 seconds, while Saloni covers the same distance in 6 minutes and 4 seconds. If both of them start together and run at uniform speed, by what distance will Sukriti win a 5 km mini marathon:
Explanation:
Sukriti runs 1 km in 5 minutes and 50 seconds = 350 seconds.
Saloni runs 1 km in 6 minutes and 4 seconds = 364 seconds.
∴ Sukriti runs 5 km in 5 × 350 = 1750 seconds
Saloni runs a distance of 1750364 ≈ 4.8 km in this time.
∴ Sukriti will win the mini marathon by 5 – 4.8 = 0.2 km = 200 m
Hence, option (b).
