Points h and f lie on circle c. what is the length of line segment gh? a.3 unitsb.4 unitsc.5 unitsd.6 units

we know that

in the right triangle gec

applying the pythagorean theorem

therefore

the answer is

the length of line segment gh is

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

5.5
