It takes a hospital employee 24 minutes to drive from home to the hospital, a distance of 16 miles. What is the employee's average rate of speed?

r = 40 miles / hour

Step-by-step explanation:

Formula

d = r * t

Givens

d = 16 miles

t = 24 minutes = 24 / 60 minutes in an hour = 0.4 hours

r = ?

Substitute and solve

16 miles = r * 0.4 hours Divide by 0.4

16/0.4 = r Switch sides

r = 16/0.4

r = 40 miles / hour
