Trina buys 3.5 yards of fabric for a sewing project she is working on. The fabric costs $4.25 per yard. How much will it cost her to buy the fabric, to the nearest penny?

$14.88

Step-by-step explanation:

if trina buys 3.5 yards at $4.25 per yard, you multiply the price by the quantity to get $14.875 but money doesn't work that way so you round to $14.88

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
