Answer:
20 miles per hour
Step-by-step explanation:
traveling against the wind was 160mph (400/2.5)
traveling with the wind was 200mph (400/2)
going against the wind is going in the negative direction of the wind speed, and going with the wind is going in a positive direction of the wind speed, therefore the wind speed is |direction1-direction2|/2, which would be |200-160|/2 = |40|/2 = 20mph
(180mph is neutral speed with no wind, with wind affecting this neutral speed ±20mph)
