Question 893337: a quarterback throws a pass that travels 44 yd with the wind in 2.2 sec. If he had thrown the same pass against the wind, the football would have traveled 22 yd in 1.6sec. Find the speed of a pass that the quarterback would throw if there were no wind.
The speed of the pass if there were no wind would be about __yd/sec

a quarterback throws a pass that travels 44 yd with the wind in 2.2 sec. If he had thrown the same pass against the wind, the football would have traveled 22 yd in 1.6sec. Find the speed of a pass that the quarterback would throw if there were no wind.
***
let x=speed of pass with no wind
let c=speed of wind
x+c=speed of pass with the wind
x-c=speed of pass against the wind
..
x+c=44/2.2(yds/sec)=20(yds/sec)
x-c=22/1.6(yds/sec)=13.75 (yds/sec)
add
2x=33.75
x=16.875
Find the speed of a pass that the quarterback would throw if there were no wind=16.875 (yds/sec)

This problem assumes the speed of the wind is added to the speed of the ball.
That is not true, it's not that simple.
