Question

A rockets speed is 2 1/3 miles per second. How fast is this in miles per hour?

Answer 1

I think it might be 140 mph. 2 1/3 as a decimal is 2.3333. So, you multiply that by 60. I'm sorry if it's wrong. lol.

Answer 2

1 hour = 60 min = 3600 sec
so 1 mile/sec = 1 mile/(1/60) min = 1 mile/(1/3600)hr = 3600 mile/hr
