74 - 96 million cats are owned
Answer:
-88 mph
Step-by-step explanation:
We can use the relation ...
time = distance/speed
to compare the times in the two directions.
![\dfrac{140}{200+w}=\dfrac{360}{200-w}\\\\140(200-w)=360(200+w)\\\\200(140-360)=w(360+140)\\\\w=\dfrac{200(-220)}{500}=-88 \quad\text{miles per hour}](https://tex.z-dn.net/?f=%5Cdfrac%7B140%7D%7B200%2Bw%7D%3D%5Cdfrac%7B360%7D%7B200-w%7D%5C%5C%5C%5C140%28200-w%29%3D360%28200%2Bw%29%5C%5C%5C%5C200%28140-360%29%3Dw%28360%2B140%29%5C%5C%5C%5Cw%3D%5Cdfrac%7B200%28-220%29%7D%7B500%7D%3D-88%20%5Cquad%5Ctext%7Bmiles%20per%20hour%7D)
The wind speed is -88 miles per hour.
_____
The problem statement tells us the travel is slower <em>with</em> the wind than <em>against</em> the wind. Hence "with the wind" must be subtracting from the net speed. That is, the wind speed is negative.
