An accountant often eats lunch at a restaurant that is 3/8 mile from her office. She makes the walk in 7 1/2 minutes. At the same rate, how long will it take her to walk the two miles from her home to her office?

Answer: 40 minutes

====================================================

Work Shown

3/8 = 0.375

7 1/2 = 7 & 1/2 = 7 + 1/2 = 7 + 0.5 = 7.5

Each decimal value is exact without any rounding done to it.

(0.375 miles)/(7.5 minutes) = (2 miles)/(x minutes)

0.375/7.5 = 2/x

0.375x = 7.5*2

0.375x = 15

x = 15/0.375

x = 40 minutes
