A can run 1.5 km distance in 2 min 20 seconds, while B can run this distance in 2 min 30 sec. By how much distance can A beat B?

a) 90 m
b) 100 m
c) 120 m
d) 180 m

• A takes time 2.20 minutes=140sec
  B takes time 2.30 minutes=150sec
  diffrence= 150-140=10sec
  
  now we are to find distance covered in 10 sec by B
  150sec=1500m
  1sec=10m
  10sec=10x10=100m

• A can beat B by 10 sec
  Distance covered by B in 10 sec = (1500 * 10) / (150)
  = 100 mts
  
  here 150sec is the value of B i.e 2min 30 sec = 150 secs

• Ans: option b)100m
  Explanation:
  A runs 1500 m in 2 min 20 s=140 s
  B runs 1500 m in 2 min 30 s=150s
  So in 140 s ,B would have covered distance=(1500*140)/150=1400 m
  So A beats B by=1500m-1400m=100m.
