Practice with circumference and arc length.
Circle O has a círcumference of 884 cm.
What is the length of the radius of the circle?
cm

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

the correct answer is d

hope this

18.8cm hope i at all
