An array shows objects in equal rows. You can use the Commutative Property of Multiplication to multiply the numbers in any order.
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.

If Jim drives 25miles/hr and he is 30 miles away you would need to solve for the number of hours it would take to get there. So, you can set up a proportion: 25miles/1hr=30miles/xhr cross multiply to get 25x=30 divide both sides by 25 and your answer is 1.2 hours.
32/7
Because 4 x 7 = 28
28+4=32
32/7
