Question 636126
One high-speed jet travels 100 miles per hour faster than another.
 When one plane travels 2000 miles, the other travels 1500 miles.
 Find the speed of each plane.
:
Let s = speed of the slower plane
then
(s+100) = speed of the faster
:
Write a time equation: time = dist/speed
:
{{{1500/s}}} = {{{2000/((s+100))}}}
Cross multiply, find s
