Question 957680: Two planes leave Charlotte and Raleigh at the same time each going to the other city. One plane flies 25 miles per hour faster than the other. Find the airspeed of each plane if the cities are 275 miles apart and the planes pass each other after 40 minutes of flying time. Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! Two planes leave Charlotte and Raleigh at the same time each going to the other city. One plane flies 25 miles per hour faster than the other. Find the airspeed of each plane if the cities are 275 miles apart and the planes pass each other after 40 minutes of flying time.
***
let x=speed of slower plane
x+25=speed of faster plane
x+(x+25)=2x+25=speed at which the two planes are approaching each other
travel time=distance/speed
2(2x+25)=3*275
4x+50=825
4x=775
x=193.75
x+25=218.75
speed of slower plane=193.75 mph
speed of faster plane=218.75 mph
