What is the speed of a helicopter that traveled 1200 miles in 7 hours

The answer is 171 m/h

Explanation:

Speed relates to positional change with time, that is, it expresses the distance traveled in a given time.

The speed is expressed as

The helicopter has to travel 1200 miles (distance) in 7 hours (time). Then we can replace the values in the velocity formula.

Therefore the helicopter speed is equal to 171 m/h

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
