In a 100 m race, Kamal defeats Bimal by 5 seconds. If the speed of Kamal is 18 Km/h, then the speed of Bimal is :
-
- 15.4 km/h
- 14.5 km/h
- 14.4 km/h
- 14 km/h
Correct Option: C
Time taken by Kamal to run 100 m = 100 / 18 x 5 / 18 = 20 s Therefore, time taken by Bimal to run 100 m = 20 + 5 = 25 s
Hence, Bimal’s speed = 100 / 25 = 4 m/sec = 4 x 18 Km/h = 14.4 Km/h
