Answer
The plane travels 5.25 miles per minute or 315 miles per hour.
Solution
To find the unit rate, divide the number of miles by the number of minutes.
Calculation:
420 miles ÷ 80 minutes = 5.25 miles per minute
This means the plane travels 5.25 miles in one minute. You can also convert this to miles per hour by multiplying by 60 (since there are 60 minutes in an hour):
5.25 miles/minute × 60 minutes/hour = 315 miles per hour
So, the unit rate is 5.25 miles per minute or, equivalently, 315 miles per hour.

First, let's find out how many miles the plane travels per minute. To do this, divide the total distance (420 miles) by the total time (80 minutes). That gives us a rate of 5.25 miles per minute. So, with a bit of math magic, we see this plane is zooming through the skies at a cool 5.25 miles every single minute! Now, if you want to bring this rate into hours, multiply the minutes by 60 since there are 60 minutes in an hour. Doing the math, we discover the plane travels 315 miles per hour! That's some serious speed! So whether you're planning a flight or just curious, knowing the speed can really put things into perspective!
