a small airplane flies for two hours with a headwind and travels only 140 miles.The plane then turns around and flies for 3 hours with a tailwind,maintaining the same speed for 330 miles.Let r represent the speed of the airplane in miles per hour and w represent the speed of the wind in miles per hour

Write a system that can be used to find the speed of the airplane and the speed od the wind.

Please help!

Answer 1

r-w = 140/2

r+w = 330/3
