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)

Answer:
A. 20
Step-by-step explanation:
To solve this you must know that the angles marked are vertical angles and are congruent. So, you should set them equal to each other
x+40=3x
you would subtract x from both sides
40=2x
and then divide 2 from both sides
20=x

Given that the extended ratio of the lengths of the triangle is given by 1:2:5 and the perimeter is 32ft, the actual length will be as follows:
1+2+5=8
1/8*32=4 ft
2/8*32=8 ft
5/8*32=20 ft
Therefore we conclude that the longest side is 20 ft
