Question

One lap around a parking lot is 3/10 mile. This represents 15% of the total distance Gregory ran.

Answer 1

We represent the total distance that Gregory ran by x such that 15% of the distance traveled by Gregory is 3/10 mile. Mathematically,
                                  (0.15)(x) = 3/10
The value of x from the equation is 2. Thus, the answer to this item is 2 miles.
