Distance = Rate × Time

speed in miles per hour. Again, we can set up a proportion to solve. So, 2/(2/15) = x/1. Cross mulitply to get 2 = (2/15)x. Dividing by 2/15 on both sides of the equation gives us x = 15 miles per hour. Alternatively, since rate = distance / time, we can take 2 miles divid-ed by 2/15 hours to get 15 miles per hour. ................
