lutik1710 [3]

Answer: The perimeter of Martha's wooden border = 44 feet.

Step-by-step explanation:

Given: The formula to find the perimeter = 2w + 2l. , where w = width and l = length

If l= 12 feet and w = 10 feet

Then, the perimeter of Martha's wooden border = 2(10)+2 (12) feet

The perimeter of Martha's wooden border = 20+24 feet

The perimeter of Martha's wooden border = 44 feet

Therefore, the perimeter of Martha's wooden border = 44 feet.

How long does a car traveling at 70 mph take to travel 88 miles, in hours

dybincka [34]

So,

Obviously, the car will travel 70 miles in one hour. So after one hour, the car will have traveled 70 miles. That leaves 18 miles.

The time it will take for the car to go another 18 miles will be 18 divided by 70.
$\frac{18}{70}$

Simplify.
$\frac{2*3*3}{2*5*7}$
$\frac{3*3}{5*7}$
$\frac{9}{35}$

Divide.
≈ 0.25714

So a car traveling at 70 mph will take approximately 1.25714 hours or 1.26 hours to travel 88 miles.
