A commuter plane flies to a small town from a major airport. The average speed flying to the small town was 250 mph and the average speed returning was 150 mph. The total flying time was 4 hrs. Find the distance between the two airports.
:
Let d = distance between the two airports
:
Write a time equation: Time = dist/speed
:
+ = 4
:
Multiply equation by 750 to get rid of the denominators:
3d + 5d = 4(750)
8d = 3000
d = 3000/8
d = 375 miles
;
Check our solution:
375/250 + 375/150 =
1.5 + 2.5 = 4
