In the figure below, GRAH is a rectangle, RA=7, and GA=10. Determine AH.

7.14 to the nearest hundreth

Step-by-step explanation:

Using the Pythagorean Theorem,

From the question,

GA=10

RA=7

Also, RA is parallel and equal to GH.

This implies that, RA=GH=7

By substitution we obtain,

Subtracting 49 from both sides.

Taking positive square root of both sides.

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
