Across country runner covers 2.5 miles in 12.5 minutes what is the runners average speed in miles per hour

Answer:

The average speed of the runner is 12 miles per hour.

Step-by-step explanation:

Given:

A cross country runner Covers =2.5 miles

Time Taken = 12.5 minutes  

To Find:

The runners average speed in miles per hour=?

Solution:

Now, we know that,

Distance = speed x time

Then, 2.5 miles = average speed x 12.5 minutes  

=>

=>

=>

=>

=>average speed = 12  

Hence, the average speed of the runner is 12 miles per hour.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

265 words per minute

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

    200 words per minute

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
