Rachel ran 1/2 mile in 4 minutes. At this rate, how many miles can she run in 15 minutes?

A 1(7/8)

The proportion (1/2) mile/4minutes = x miles /15minutes models this situation. Cross multiply 1/2 * 15 =4x, so 15/2 =4x and x = 15/2 * 1/4 =15/8=1(7/8) miles.

Very cool and useful . It also tells you why you got the question wrong and how to solve it . Another cool thing is that it gives you a tracking sheet of your goals and study time
