Choose the true statement about to the square root of 165 . a) it lies between 8 and 9 on a number line. b) it lies between 11 and 12 on a number line. c) it lies between 12 and 13 on a number line. d) it lies between 13 and 14 on a number line.

144 < 165 < 169

sqrt (144) < sqrt(165) < sqrt (169)

12< sqrt(165) < 13

C) It lies between 12 and 13 on a number line.

Choice C

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

i think the answer is b.

step-by-step explanation:

not 100% sure though.
