Question

Express by chain rule, a speed of 45 mile per hour in feet per second.​

Answer 1

Answer:

Convert to Feet per Second

Divide your speed in feet per minute by 60. This is the number of seconds in a minute. Therefore, the result is your speed in feet per second. For example, 5,280 feet per minute divided by 60 seconds in a minute equals 88 feet per second.
