Question 247800: dto = dreturning
Example: With a 30-mph head wind, a plane can fly a certain distance in 6 hours. Returning, flying opposite direction, it takes one hour less.
Equation: (r-30)6=(r+30)5 Answer by solver91311(24713) (Show Source):
So what is your question? If you want to know the speed the plane flies when there is no wind, just solve the equation for . Then if you need the distance flown, subtract 30 from and multiply times 6, or add 30 to and multiply by 5.
