In other words, the distance you drove is equal to the rate at which you drove times the amount of time you drove. For an example of how this would work in real life, just imagine your last trip was like this:
>You drove 25 miles—that's the distance.
>You drove an average of 50 mph—that's the rate.
>The drive took you 30 minutes, or 0.5 hours—that's the time.
