PLEASE HELP I WILL MARK AS BRAINLIEST

I think the answer is KL, KJ, JL

Step-by-step explanation:

if treated as a right triangle (angle k is 92 degrees instead of 90) then JL would be the hypotenuse which would make it the longest. KL would be the shortest side (angle L acts as a 60-degree angle). this would mean KJ would be the middle length.

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

70
