on the first day of a trip, Ricky drove 800 miles in 20 hours. At that rate, how many miles did he drive in 1 hour?
mr Goodwill [35]

We are trying to find miles/hour, which shows that we are going to be dividing the total number of miles by the total number of hours. Thus, in this case, the miles/hour rate will be:

\dfrac{800 \,\textrm{miles}}{20 \,\textrm{hours}} = 40 \dfrac{\textrm{miles}}{\textrm{hour}}


He drove 40 miles in one hour.

kondor19780726 [428]

I say, just take a minute and remember why you are doing it. If you love it, just remember the love that you get from it. If you don't love it, then just think of it as getting experience for something else in life.

I get nervous before my cross country/track/half marathon races and all I think about is why I'm doing it in the first place.

Hope it helps!
