A plane flies 2,000 miles from Chicago to Los Angeles wit ha 50 mph tail wind in 3.25 hours. Returning against that same wind, it takes 4 hours. What is the speed of the plane if there is no wind?

Question

lgbasallote · Answer

downstream speed = 2,000/3.25

downstream speed = speed of plane + tail wind

upstream speed = 2,000/4

upstream speed = speed of plane - tail wind

does that help?
