A can run 1.2 km distance in 2 min 30 seconds, while B can run this distance in 2 min. By how much distance can B beat A ?

• A=1200m/150sec=8m/s,B=1200m/120sec=10m/s,
  at 2min B travel 1200m by that time A travel distance=8*120=960,
  1200-960=240.

• 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
