8. Arlie is on an airplane that has traveled 420 miles in

I of an hour. At this rate, how far will the airplane

travel in the next hour?

We can define speed as:

Speed = distance/time.

(time says 1 of, so i will use 1/3 of an hour, the math will work for any number, you can just change it)

Here the distance is 420 miles and the time is 1/3 hour, so the speed is:

S = 420mi/(1/3)h = 420mi/(1/3)h or 1260 mph.

Then, in a complete hour the airplane will travel other 1260 miles
