Question 431703: One plane traveled 800 miles in the same time a second plane traveled 1,000 miles. The rate of the second plane was 50 mi/h faster than the rate of the first plane. How fast did each plane fly? Answer by mananth(16946) (Show Source):
t=d/r Time Plane A = Time Plane B
800/x=1000/(x+15)
Cross multiply
800(x+15)=1000* x
800x+12000=1000 x
1000x-800x=12000
200x=12000
/200
x=60 Plane A mph
75 Plane B mph
