The average speed on the way to the airport was 100mph, and the average speed returning was 150mph.
Find the distance between the two airports if the total flying time was 5 hours.
:
Let d = distance between the two airports
:
Write a time equation; Time = dist%2Fspeed
:
to time + return time = 5 hrs
d%2F150 + d%2F100 = 5
multiply equation by 300, results:
2d + 3d = 300(5)
5d = 1500
d = 1500%2F5
d = 300 mi between airports

;
Check solution
300%2F150 + 300%2F100 = 5
