Question

With a tail wind, a plane traveled 800 mi in 5 hours. With a head wind, the plane traveled the same distance in 8 hours. Which system of equations could be used to solve this problem?

Answer 1

`{(5(p+a) = 800),(8(p-a)=800):}`

Explanation:

By letting
`color(white)("XXX")p =` plane's speed relative to the air around it
`color(white)("XXX")a =` air speed of wind
the above equations are a direct translation of the the problem statements.
