Question 927074: Two airplanes leave the Atlanta airport at the same time traveling in opposite directions. One plane travels 30 miles per hour faster than the other. After 3 hours, the planes are 3150 miles apart. What is the rate of each plane?
Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website!
x = speed airplane one
y = speed airplane two
y = x + 30
---
s = d/t
---
relative speed of the two airplanes:
x + y = 3150/3
x + x + 30 = 3150/3
2x = 3150/3 - 30
x = (3150/3 - 30 )/2
---
answer:
x = 510 mph
y = 510 + 30 = 540 mph
