Anusha is walking on a hiking trail at a rate of 3/4 miles in 1/4 hour. At this rate, how far will Anusha walk in an hour?

At this rate, Anusha will walk 3 miles in an hour. You can find this in two ways, the first being simply multiplying the 3/4 by 4 because it is 1/4 of the destination time. You can also do 3/4 mile over 15 minutes and a variable of your choice over 60 minutes and cross multiply to get 15a=45. Next, divide 45 by 15 and you get "3," meaning 3 miles were traveled.

3 miles. Using cross-multiplication, 3*4 = 12 and 4*1 = 4, so 12/4 = 3.
