1. Find the distance from point E (-4,-3) to FH

Step-by-step explanation:

(-4,-3) is

4 - 4 =0 ok

4 - 3 = 1

4 is you the distance  from point

and Osos if you type distance from point calculator  you can type you point and see the distance point

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

each side has a different length.
