Which additional information, if true, would help to prove that ΔLMP ≅ ΔNMP by HL? Check all that apply.
A. Point P is the midpoint of MK.
B. Line MK is the perpendicular bisector of LN.
C. ML ≅ MP
D. ML ≅ MN
E. PK ≅ PK

My answers are B and D

Step-by-step explanation:

B and D are correct.

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
