Question

of the speed 20km/h and 5m/s, which is greater?​

Answer 1

20 KMPH is greater......

Answer 2

Speed 20km/h is greater.

5m/s

To know which is greater we need make the units same. To do that we need to multiply 5m/s  with 18/5

5m/s = 5(18/5)  = 18 Km/h

Since 20Km/h > 18 Km/h

=> 20 KMPH > 5MPS
