Solution:When A goes 100 meters, then B goes 90 meters.∴ Ratio of speed of A/B = 100/90 ⇒ A/B 10/9
∴ A starts 10 meters behind the starting line.
∴ A will cover the distance = 100+10= 110 meters
In same time and with same speed B will cover the distance
= 110/10 × 9 = 99 meters.
So, in new race A beats B by 1 meter.
