(312 - 0.75)
Х

Option D.

Step-by-step explanation:

It is given that VWXY is a rhombus, VW = 6m-12 and WX = 4m+4.

We know that all sides of a rhombus are equal. So,

Isolating the m on left side, we get

Dividing both sides by 2, we get

The value of m is 8. So, each side of the rhombus is

Therefore, the correct option is D.

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

an altitude of 15,000 feet
