Answer

Answer:

D. 45.36 feet per second

Explanation:

Step1: Convert miles to feet

Since 1 mile = 5280 feet, for 30 miles, the number of feet is $30\times5280 = 158400$ feet.

Step2: Convert minutes to seconds

There are 60 seconds in a minute. So 58.2 minutes is $58.2\times60=3492$ seconds.

Step3: Calculate speed in feet - per - second

Speed $v=\frac{\text{distance}}{\text{time}}$. So $v = \frac{158400}{3492}\approx45.36$ feet per second.
