Geri is in a marathon race it took her 3 hours and 28 minutes to run 26 miles how many minutes did it take her to run 1 mike if she ran at the same rate for the whole race

It will take 8 minutes

Step-by-step explanation:

3 hours 28 minutes = how many minutes

3 hours * 60 minute/hour = 180 minutes

3 hours 28 minutes =180 +28 = 208 minutes

We can use proportions to solve

26 miles               1 mile

   =  

208 minutes           x minutes

Using cross products

26 * x = 208 *1

26x = 208

Divide by 26

26x/26 = 208/26

x = 8

It will take 8 minutes

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
