A pilot flies 630 miles with a tailwind of 35 miles per hour. Against the wind, he flies only 455 miles in the same amount of time. Find the rate of the plane in still air.

Answer 1

Answer:

Step-by-step explanation:

630/n+35=455/n-35

630n-22050=455n+15925

175n=37975

n=217

The plane goes 217 mph in still air..
