Answer:

1260

Step-by-step explanation:

Given : Jackie ran fifty yard at an average speed of 21 feet per second.

To Find:  what was her average speed in feet per minute?

Solution:

Speed of Jackie = 21 feet per second.

60 second = 1 minute

1 second = [tex]\frac{1}{60} minute[/tex]

Now we are supposed to convert the speed in feet per minute

Now , 21 feet per second = [tex]\frac{21}{\frac{1}{60}}[/tex]feet per minute

                                          = [tex]1260[/tex] feet per minute

Hence her average speed in feet per minute is 1260 feet per minute

Thus Option A is correct.
