Suppose two planes leave the airport at the same time, one traveling east and the other traveling west. If the planes are 2100 mi apart after 2 hours and one plane travels 50 mph faster than the other, find the rate of each plane.

Suppose two planes leave the airport at the same time, one traveling east and the other traveling west. If the planes are d mi apart after t hours and one plane travels k mph faster than the other, find the rate of each plane.

__________________rate______________time______________distance
EAST_______________r________________t_________________rt
WEST______________r+k______________t_________________(r+k)t
Total___________________________________________________d

Solve this symbolically first, for r. Once this is solved, substitute according to the given information.

r=unknown
d=2100
t=2
k=50

Suppose two planes leave the airport at the same time, one traveling east and the other traveling west. If the planes are 2100 mi apart after 2 hours and one plane travels 50 mph faster than the other, find the rate of each plane.

Let speed of slower plane be S
Then speed of faster plane = S + 50
We then get: 2S + 2(S + 50) = 2,100
2S + 2S + 100 = 2,100
4S = 2,000
S, or slower plane's speed = , or mph
Faster plane's speed: 500 + 50, or mph
