There are some hats in a box. 1/6 of them are red, 1/3 of blue, and 3/7 of the remainder are green. if there are 27 green hats, how many hats are there altogether

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

answer: d. $20
