a.62.05 miles per hour
b.63.2 miles per hour
c.64.05 miles per hour
d.65.8 miles per hour
e.66.5 miles per hour

65.8 miles per hour

Step-by-step explanation:

Given : A tractor-trailer travels 205.296 miles in 3.12 hours.

To Find:What is the speed at which the tractor-trailer is traveling

Solution:

Distance traveled = 205.296 miles

Time taken = 3.12 hours.

So, Speed =

So, Speed =

Speed =

Hence the speed at which the tractor-trailer is traveling is 65.8 miles per hour

So, Option D is correct.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

it is x=-4
