Question
In a circular race of 750 m, X and Y start from the same
point and at the same time with speeds of 9 km/h and 13.5 km/h, respectively. If they are running in the same direction then, when will they meet again for the first time on the track?Solution
Track length = 750 m
Speeds: X = 9 km/h = 2.5 m/s, Y = 13.5 km/h = 3.75 m/s
Relative speed (same direction) = 3.75 â 2.5 = 1.25 m/s
Time to meet = 750 Ă· 1.25 = 600 seconds = 10 minutes
