When a plane flies with the wind, it can travel 800 miles in 2 hours. When the plane flies in the opposite direction against the wind, it takes 2.5 hours to fly the same distance. Find the average velocity of the plane in still air and the average velocity of the wind.
The average velocity of the plane in still air is
mph.

sup

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
