Let:
x = Chemistry textbooks sold
y = Physics textbooks sold

The number of chemistry books sold was three times the number of physics textbooks sold, so:
Let:
Replace (2) into (1):
Replace the value of y into (2):
Hey You!
1.5 ft = 18 inches
There is no difference between the distance the two animals traveled.
