Mackenzie ran the olympic marathon of 26 1/5 miles in a time of 5 4/5 hours. How far did she run in a 1 hour?​

Step-by-step explanation:

v=d/t (average velocity equals distance divided by time)

26.2mi/5.8h=4.5mi/h

So Mackenzie runs approximately 4.5 miles in an hour (rounded to nearest tenth of a mile)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
