Feather head head heather 7 1/2 cups of bird food. if her bird feeder holds 1/2 of a cup of bird food how manyb times can feather head heather fill the bird feeder

15 times

Step-by-step explanation:

I assume that your question is:

Heather has 7.5 c bird food. The feeder holds 0.5 c bird food. How many times can Heather fill the bird feeder?

7.5/0.5=7.5*2=15

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
