The answer is A so pick that
To grandparents house :
140/56 = 2.5 hours
Return trip :
140/50 = 2.8 hours
Total time : 2.8+2.5 = 5.3 hours
There is 16 squares on each side for 16 times 16 is 256
The original equation is
P=2L+2W
We will just switch the unknowns around. To find width (W), we must isolate it in the equation by moving 2L over to the other side:
P-2L=2W
(P-2L)/2=W
W=(P-2L)/2
There you go!!
