flying to myrtle beach, sc, a plane averaged 312 mph flying into a strong wind. on the return trip flying with a tailwind, the plane averaged 426 mph. write a system of equations to represent the situation
***
let x=speed of plane in still air
let c=speed of wind
..
x-c=312 mph
x+c=436 mph
add:
2x=748
x=374 mph
..
subtract:
2c=124
c=62 mph
