A car travels 43 km in 56 minutes.

patriot [66]

Answer:

$\displaystyle v=46.07\ Km/h$

Step-by-step explanation:

<u>Speed</u>

The speed is the ratio between the distance x traveled by an object and the time t taken.

$\displaystyle v=\frac{x}{t}$

The car travels x=43 Km in t=56 minutes. We are required to express the speed in Km/h. The time needs to be expressed in hours:

$t = 56 / 60 = 0.933\ h$

Now apply the formula:

$\boxed{\displaystyle v=\frac{43}{0.933}=46.07\ Km/h}$

Recall that the perimeter of a rectangle is P=2(W+L), where W is the width and L is the length. The length of a rectangle is 23

maxonik [38]

Answer:

Length = 6 + 23 = 29 feet

Step-by-step explanation:

Width = x

Length = x + 23

2x + 2(x+23) = 70

2x + 2x + 46 = 70

4x = 70-46

x = 24/4

x = 6
