Zolol [24]

Answer:

The unit rate in miles per hour = <em>1.4 miles/hr</em>

Step-by-step explanation:

Given that:

Distance walked by Boardman family = Two over five of a mile = $\frac{2}{5}\ miles$

Time taken by Boardman family = Two over seven of an hour = $\frac{2}{7}\ hour$

To find:

The unit rate in the miles per hour = ?

Solution:

Formula for the rate or the speed can be given as:

$Speed = \dfrac{Distance}{Time}$

Putting the values:

$\Rightarrow \dfrac{\frac{2}5}{\frac{2}7}\\\Rightarrow \dfrac{7}{5}\\\Rightarrow \bold{1.4\ miles/hr}$

So, the unit rate in miles per hour = <em>1.4 miles/hr</em>

The perimeter of a rectangle is 200 yards. what are the dimensions of the rectangle if the length is 80 yards more than the? wid

liq [111]

P = 2(L + W)
P = 200
L = W + 80

200 = 2(W + 80 + W)
200 = 2(2W + 80)
200 = 4W + 160
200 - 160 = 4W
40 = 4W
40/4 = W
10 = W.........the width is 10 yds
