In a 400-metre race, Ashok beats Bipin and Chandan respectively by 15 seconds and 25 seconds. If Ashok beats Bipin by 150 metres, by how many metres does Bipin beat Chandan in the race?
Explanation:
Ashok beat Bipin by 150 metres or 15 seconds. ∴ Speed of Bipin = 150/15 = 10 m/s
Bipin takes = 400/10 = 40 seconds to complete the race. Time taken by Ashok to complete the race = 40 - 15 = 25 seconds Time taken by Chandan to complete the race = 25 + 25 = 50 seconds
Distance travelled by Chandan in 40 seconds = 400/50 × 40 = 320 metres.
∴ By the time (40 secs) Bipin completes the race, Chandan has completed 320 m and hence Bipin beats Chandan by 80 meters.
Hence, option (a).
