The x- 43 hyper-x is one of the fastest aircraft in the world. It can reach a maximum speed of 6750 mph. What is its maximum rate of speed in miles per second ?? Please explain how you got your answer

Answer 1

There are 3600 seconds in 1 hour, so the fraction (1 hour / 3600 seconds) is equal to exactly 1. Multiply (6750 miles/hour) by (1 hour / 3600 seconds) and you get 1.875 miles/second.
