AFCAT II 2020 Solved Paper

let the speed of faster race and slower racer is 2x and x.
By assuming the slower racer to standstill the relative speed of slower racer 2x−x=x
Then he covers one round in 5min.
So, x=‌

1000

5

=200= speed of slower racer
Then, speed of faster racer =2x=400
Hence time taken by faster race to complete the race =‌

4000
