<PRE><B>Question 433815</B>
Travel by plane: It takes a plane flying at 450 mph 25 minutes longer to travel a certain distance than it takes a second plane to fly the same distance at 500 mph. Find the distance.
..

let x=distance both planes traveled
Time of travel = distance/speed
x/450-x/500=25min=25/60 hrs
(500x-450x)/450*500=25/60
150x=25*450*500/60
x=93750/150=625 miles
ans:
distance both planes traveled=625 miles</PRE>
