SOLUTION: 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

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

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.
