Answer : Option A
Explanation :
Speed of B = Distance / time
= 100 / 45 = 20 /9 m/s
Distance = speed * time
Distance covered by B in (45 - 36) = 9 seconds:
∴ A beats B by 20 meters.
Solution 2:
Distance covered by B in 45 seconds = 100 meters
Distance covered by B in 9 seconds = (100/45) * 9 = 20 meters
So, when A covers 100 meters in 36 seconds, B was 20 meters away from the winning post. Thus, A beats B by 20 meters.
