r = 60 m/h t = 2 h D = r t = (60m/h) x (2h) = 120 mi
Rate. The official equation is r=d/t, or rate=distance divided by time. Example: A train is traveling about 450 miles to Spain. It gets there in 5 hours. Set up your equation: r=d/t r=450/5 r=90 which means that the train was traveling at a rate/speed of 90 miles per hour. If you are unsure of the answer just plug it in and check it. 90=450/5 90=90 True Now you have verified your equation, and the answer is that the train was traveling 90 mph.
