How fast did each of the airplanes travel?
Two airplanes start a 1000-mile journey to another city. One airplane travels 50 mph. faster than the other airplane and arrives at the city an hour before the slower plane. How fast did each of the airplanes travel?

d = vt
vt = 1000 => t = 1000/v
(v + 50)(t - 1) = 1000
(v + 50)(1000/v - 1) = 1000
v = 200
v + 50 = 250
