A covers 1200m in 150sec(2min 30sec) with speed of 8m/s
B covers 1200m in 120sec(2min) with speed of 10m/s
if in 10m/sec covers 1200m
in 1m/sec covers (1200/10)m
in 8m/sec covers ((1200/10)*8)m=960m
total distance covered by A with 8m/sec is 960m
then B beats A by 1200-960=240m

A takes time 1.20 minutes=80sec
B takes time 2 minutes=120sec
diffrence= 120-80=40sec

now we are to find distance covered in 40 sec by B
120sec=1200m
1sec=10m
40sec=40x10=400m

A takes time 2.30 minutes=150sec
B takes time 2 minutes=120sec
difference= 150-120=30sec

Now distance covered in 30 sec by B
120sec=1200m
30sec=1200/120*30=300m
