Answer:
Unit rate of plane = 525.4 miles per hour
Explanation:
We have given,
Distance travel by plane = 3,625.26 miles
Time taken by plane = 6.9 hours
We need to find plane's unit rate.
i.e Unit rate = distance travel by plane/ time taken by plane
Unit rate = 3,625.26 / 6.9
Unit rate = 525.4 miles / hour
So the unit rate of plane we got is 525.4 miles per hour
