Answer:
0.857 miles in 1 hour
Step-by-step explanation:
It is given that,
A crew of highway workers paved 12 mile in 14 hour.
We need to find how much will they pave in 1 hour if they work at the same rate.
14 hours = 12 miles
To find how much they pave in 1 hour, we must divide 12 by 14 as follows :

Hence, they pave 0.857 miles in 1 hour.0.857 miles in 1 hour.

Answer:
Step-by-step explanation:
As with all word problems we first have to convert it to an equation or equations.
L = length of the Rectangle and W = its width
So L = 2 * W
A = area of the rectangle which is 128 cm^2
So A = L * W = 128 cm^2
substitute 2W for L from the 1st equation to give A = 2 * W * W = 2 * W^2 = 128 cm^2
Thus W^2 = 64 cm^2
finally W = 8 cm and therefore L = 2 * W = 16 cm
The perimeter P = 2 * (L+W) = 2* (8cm + 16cm) = 2 * 24cm = 48 cm
Step-by-step explanation: hopefully this helps
