Dist = 100m

Speed of Abhay = 2m/s

Speed of Rohan = xm/s

Since, Rohan has a start of 5m he has to cover only 95m but Abhay has to cover 100m

Time taken by Abhay to cover 100m = Dist/Velocity

= 100/2 = 50s

Since, Abhay beats Rohan by 10s, Rohan takes

50+10 = 60s to cover 100m

Therefore, Rohan's speed = Dist/Time = 100/60

= 10/6 = 1.67m/s
