divide 96 by 4 to get the length of each side then multiply that answer by itself
T = k/R where k is the constant of variation, T=time and R=speed.
Plug in the given values:-
12 = k/60
k = 12*60 = 720
So the equation of variation is T = 720/R
At 85 mph we have
T = 720 / 85 = 8.47 hours (answer)
Answer: real numbers have to be whole (maybe negative) but no fractions or decimal answers. 23 is also an integer. so the answer is A
