Question

A rocket needs to reach a speed of 28,300 km/hr in order to get into orbit around Earth. How fast is this in miles per second.

Answer 1

Answer:

Step-by-step explanation:

1 km = 0. 621371 miles

28,300 km = 28,300* 0. 621371 miles = 17,584.7993 miles

1 hour = 60 *60 seconds  = 3,600 seconds

speed of 28,300 km/hr =

17,584.7993 miles / 3,600 seconds ≈ 4.88 miles / second
