Two planes are 1620 miles apart and ate traveling toward each other. One plane is traveling 120mph faster than the other plane. The planes pass each other in 1.5h find the speed of each plane.
***
let x=speed of slower plane
x+120=speed of faster plane
x+x+20=2x+20=speed at which planes are traveling toward each other
distance/speed=travel time

3x+180=1620
3x=1440
x=480
x+120=600
speed of slower plane=480 mph
speed of faster plane=600 mph

_________________speed___________time__________distance
_________________r+120____________1.5____________(r+120)*(1.5)
__________________r_______________1.5____________r*(1.5)
Total__________________________________________1620

Simple linear equation in the one variable, r.
