<PRE><B>Question 897598</B>
two planes, which are 2265 miles apart, fly toward each other. their speed differ by 55 mph. if they pass each other in 3 hours what is the speed of each
***
let x=speed of slower plane
x+55=speed of faster plane
distance=travel time*speed
..
3x+3(x+55)=2265
3x+3x+165=2265
6x=2100
x=350
x+55=405
speed of slower plane=350 mph
speed of faster plane=405 mph</PRE>
