Sally is building a fence. She needs 234 inches of fencing material. How many yards of fencing material does she need?

6.5 yards

Step-by-step explanation:

1 yard = 36 inches

234/36 = 6.5

be more specific

step-by-step explanation:

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
