Afish swims at a speed of 12 miles per hour. a boy swims at a speed of 4.4 feet per second. 3 ft = 1 yd 5280 ft = 1 mi how much faster does the fish swim than the boy in yards per minute?

You'll need to convert both speeds into yards per minute.

12 mph = 12 mph     1760 yd    60 min
                * *
                  1 mile       1 hr

Note that "miles" cancels.  So does "hours."  Finish this work.

Then convert   4.4 ft/sec into yards per minute.

Then, finally, compare your two rates via subtraction of the smaller from the larger.
