226. A can run 2 km in 4 min 20 seconds, while B can run this distance in 4 min 34 sec. By how much distance can A beat B?

a) 100 m
b) 150 m
c) 120 m
d) 180 m

• A can beat B by 14 sec
  Distance covered by B in 14 sec = (2000 * 14) / (274)
  = 102.18 mts
  
  here 274 sec is the value of B i.e 4min 34 sec = 274 secs

• If B runs 2000 meters in 274 seconds, then how far has B run in 260 seconds.
  the ratio would be:
  2000 / 274 = x / 260
  =>2000 * 260 = 274 * x
  =>520,000 = 274 * x
  solve for x and you get x = 520,000 / 274 = 1897.810219 meters.
  then just take the difference between 2000 and 1897.810219 to get 102.189781.
