Answer:

12

Step-by-step explanation:

For our problem since we only in 10 am:

I'm going to let x=4 represent the time 10:04 am

which means I'm going to let x=17 represent 10:17am.

So when x=4, y=23 miles and when x=17,y=179 miles.

You have two points.

You can use the formula m=\frac{y_2-y_1}{x_2-x_1}.

Or just line the points up vertically and subtract them vertically, then put 2nd difference over first difference. Like this:

(    17  ,   179)

-(     4 ,      23)

-----------------------

   13          156

So the slope is 156/13=12 miles/hour.

<em>Simplify</em>

6 < 7

  • This is true

<em>Insert 3 into the equation</em>

11 - 3 < 7

<em>Simplify</em>

8 < 7

A squirrel can run a maximum speed of 12 miles per hour. At this rate how long will it take for the squirrel to run 3 miles
oksian1 [2.3K]

Answer:

Squirrel will take 0.25 hours or 15 minutes

Step-by-step explanation:

Given:

Maximum speed of squirrel = 12 miles/hour

Distance to be covered = 3 miles

To Find:

Time taken to cover the distance = ?

Solution:

We are given the distance and speed of the squirrel and we have to find the time taken by the squirrel

We are given the formula for distance

Distance = speed * time

Now to we have the values

putting in the values

3 = 12 * time

dividing both sides by 12

\frac{3}{12}=\frac{12}{12}*speed

0.25 hours = time

as one hour = 60 minutes

so

time = 0.25 * 60 minutes

time = 15 minutes

Squirrel will take 0.25 hours or 15 minutes
