June made a design with 6 equal tiles. one tile is yellow, 2 tiles are blue, and 3 tiles are purple. what fraction of the tiles are yellow or purple?

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

8 2/3 is the answer

step-by-step explanation: just use a calculator
