The average speed is the ratio of the total distance to the total time. Then the average speed of the airplane will be 698.19 miles per hour.
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
An airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph.
Then time taken for the first trip will be
t₁ = 867 / 612
t₁ = 1.4167 hours
Then time taken for the second trip will be
t₂ = 1984 / 744
t₂ = 2.6667 hours
Then the average speed is the ratio of the total distance to the total time.
The total distance will be
Total distance = 867 + 1984
Total distance = 2851 miles
The total time will be
Total distance = 1.4167 + 2.6667
Total distance = 4.0834 hours
Then the average speed will be
Average speed = 2851 / 4.0834
Average speed = 698.19 mi/h
