Vasily is flying his first solo trip. his plan is to fly round trip, 2368 miles. his flight plan factors in the wind speed of 20 miles per hour and expects that he will complete the flight in 7 hours. at what speed is vasily flying in still air? (round your answer to the nearest mile per hour.)

Let us assume that u be the speed of Vasily flying in still air. Since round trip is 2368 miles. One way will be 1184 miles.

On one side the wind speed will support Vasily and on the other side, the wind speed will oppose Vasily. Therefore, effective speeds for both the sides will be (u+20) and (u-20).

We can find the sum of times for both the sides and set the sum equal to 7 hours.

Now, our next step is to solve this equation for u.

Therefore, Vasily is flying in still air at a speed of 340 miles per hour.

yes yes yes

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
