Janet drove 395 kilometers and the trip took 5 hours. How fast was Janet traveling?

Distance = Rate * Time

We're given D = 395 and t = 5

We want Rate. We divide each side of the equation by time:
Distance / Time = Rate * Time / Time

Cancel the Time's on each side and we get:
Rate = Distance / Time

Plugging our numbers in, we get:
Rate = 395/5
Rate = 79 kilometers
