Write all the factors of number 24 and use commas to separate them

1,2,3,4,6,8,12, and 24.

Step-by-step explanation:

Well just list all the numbers that can be multiplyed or divided to get you to 24.

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
