In a kilometer race, A beats B by 25 seconds and B beats C by 15 seconds. If A beats C by 160 m, then the time taken by A to run 1 kilometer is : |
185 seconds 200 seconds 210 seconds 225 seconds |
210 seconds |
The correct answer is Option (3) → 210 seconds Distance covered by C = Speed of A × $t_A$ $=\frac{1000}{t_A+40}×t_A=840$ $⇒1000t_A=840(t_A+40)$ $⇒t_A=\frac{33600}{840}=210$ |
