How to Calculate Average Speed

If a bird was able to fly 20 miles in 60 minutes, you could say that it traveled at 20 miles per hour.

That’s pretty easy, but here’s the work showing how you would come up with that answer.

We know that 60 minutes equals one hour. So we could say where D equals 20, the distance traveled, and T equals one, because 60 minutes equals one hour.

Our formula is distance equals rate times time. I’m gonna write it once again just to show you. Distance equals 20. My rate I do not know. And my time is one.

That means that the rate was equal to 20 miles per hour.
