Problema Solution
Airplane A travels 2800 km at a certain speed. Plane B travels 2000 km at a speed 50 km/h faster than Plane A in 3 hours less time. Find the speed of each plane.
Answer provided by our tutors
2800/x-2000/(x+50)=3
2800x+140000-2000x=3x^2+150x
3x^2-650x-140000=0
x= 350 kph
plane a goes at 350 kph while plane b at 400 kph
