Point A is at (3,4) and point B is at (8, -4). What is the midpoint of line segment AB?

(5.5, 0 )

Step-by-step explanation:

Given points (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]

The midpoint of A(3, 4) and B(8, - 4) is therefore

[ 0.5(3 + 8), 0.5(4 - 4) ] = (5.5, 0 )

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
