anonymous · Answer

The answer to your Question is B. 

6.6(60seconds)=396 feet per minute

Subtract 528-396=132  Now you have your differce between the two people in feet per minute

Divide 132/5280 ( for the total number of feet in a mile)
=.025

Now multiply by 60, becuse you are still in minutes.  .025(60)=1.5 miles per hour
