How do you convert 20m sec into km hr?

Answer 1

There are 1000 meters in a kilometer(1000 m) / (1 km). There are 3600 seconds in an hour, so (1 hr) / (3600 s). you can just multiply (1 km / hr)*[(1000 m) / (1 km)]*[(1 hr) / (3600 s)] to get 0.28 m/s.

Answer 2

To convert m/s to km/h, you multiply by 3.6. So, 20 m/s is equal to 20 x 3.6 = 72 km/h.

Answer 3

1 km = 1000 meters, 1 hour = 3600 seconds. So 1 km/hr = 1000/3600 = 0.278 m/sec.

100 km/hr = 27.8 m/sec

Answer 4

Meters per second divided by 3.6 equals km/hr: 20m/sec = 20 / 3.6 = 72km/hr
