Question

A jet plane traveling at a constant speed goes 1200 mi with the​ wind, then turns around and travels for 1000 mi against the wind. If the speed of the wind is a constant 50​ mph, and the total flight took 4​ hours, find the speed of the plane. Round your answer to the nearest​ tenth, if necessary.

Answer 1

Answer:

Avg speed 550 miles per hour

Step-by-step explanation:

with the wind 1200 miles traveling

1200/(550+50) = 2 hours

Against the wind

1000/(550-50) = 2 hours
