An airplane flies from Metro City to Gotham with a tailwind that increases its normal
speed by 100 mph On the return trip, the plane must fly against this wind, which
decreases its normal speed by the same amount. The flight from Metro City takes
2.00 hours and the return trip takes 3.60 hours How far is it from Metro City to
Gotham?
OA) 1100 mi
OB) 900 mi
C) 1020 mi
D) 1200 mi

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

one set of data has more variation than the other. hope this !
