Question

The outside of a merry-go-round spins 3 km each hour. How fast is this in meters per second

Answer 1

0.83 meter per second

Step-by-step explanation:

3km/hr

1 km = 1000m

3km = 3×1000

= 3000m

60secs = 1 minutes

60minutes = 1 hr

1 hour = 60×60 = 3600secs

Hence 3km/hr = 3000÷3600

= 0.83 meter per second
