Question

In a kilometre race, A beats B by 30 seconds and B beats C by 15 seconds. If A beats C by 180 metres, the time taken by A to run 1 kilometre is what ?​

Answer 1

Answer:

$\huge\underline\bold {Answer:}$

A beats B by 30 seconds, B beats C by 15 seconds

Therefore, A beats C by (30 + 15) seconds = 35 seconds.

=> Time taken by C to travel 180 m = 45 seconds.

=> Time taken by C to cover the distance of 1 km (1000 m) = 45/180 × 1000 = 250 seconds.

Therefore, required time taken by A to cover the distance of 1 km = (250 – 45) sec = 205 sec.
