Kelly flies a distance of 2,100 Miles the trip takes 4 2/3 hours. At this rate of speed how many miles with the airplane travel 1 1/2 hours and what is the airplanes unit rate of speed in miles per hour?

450 miles per hour
Step-by-step explanation:
Kelly flies at a distance of 2,100 miles
The time taken for the trip is 4 2/3 hours
Therefore the rate of speed can be calculated as follows
= 2,100 ÷ 4 2/3
= 2,100 ÷ 14/3
= 2100 × 3/14
= 150 × 3
= 450 miles per hour
