Answer:

The average speed is $\frac{3}{35}\frac{ft}{min}$

Step-by-step explanation:

we know that

To find out the average speed divide the distance by the time

Let

s -----> average speed

d -----> the distance in feet

t ----> the time in minutes

$s=\frac{d}{t}$

we have

$d=6\ ft$

$t=70\ min$

substitute

$s=\frac{6}{70}\frac{ft}{min}$

Simplify

$s=\frac{3}{35}\frac{ft}{min}$

Please help, I am so confused

Answer:

$\huge\boxed{25.2\ m}$

Step-by-step explanation:

In order to find the length of the missing side here, we must note that these triangles are similar.

Therefore their lengths are proportionate to each other.

So,

$\frac{27.6}{11.5} = \frac{x}{10.5}$

We can solve for x by cross multiplying.

$10.5\cdot 27.6 = 289.8\\\\289.8 \div 11.5 = 25.2$

Hope this helped!
