Question

The formula d = rt gives the distance traveled in time t at rate r. A bicyclist rides for 1.25 hours and travels 32 miles
What was the bicyclist's average speed?

Answer 1

You want to find speed, which is R in the formula. Think of it as a formulae triangle.
Block out R, because you want to find that. So the formula for speed is distance divided by time, or R equals D over T. 32 divided by 1.25 hours is 25.6 miles per hour. This formula gives only the average, so that's your answer.
