A commuter plane flew to a small town from a major airport.
The plane's average speed flying to the small town was 250 mph, and its average speed
returning to the major airport was 150 mph. The total flying time was 4 hours.
Find the distance between the two airports.
~~~~~~~~~~~~~~~
Let d be one-way distance.
Time to flight to there is hours.
Time to flight back is hours.
Total time equation is
+ = 4 hours.
The setup is done.
Now our task is to solve it.
Multiply both sides by 750. You will get
3d + 5d = 3000
8d = 3000
d = 3000/8 = 375 miles.
ANSWER. One way distance is 375 miles.
CHECK. + = 1.5 hours + 2.5 hours = 4 hours. ! Correct !
