Answer:
Option C, x = 35
Step-by-step explanation:
<u>If two angels are supplementary, they add up to 180</u>
<u />
<u>Step 1: Make an equation</u>
<em>3x + 15 + 60 = 180</em>
<em />
<u>Step 2: Solve for x</u>
3x + 15 + 60 = 180
3x + 75 - 75 = 180 - 75
3x / 3 = 105 / 3
<em>x = 35</em>

Answer: Option C, x = 35
Caroline should have thought of what she wanted to do first. That way, it reduces Caroline's percentage.
I'm not all that familiar with that sort of representation, but I guess 3 3/4 = 15/4 and 2 1/6 = 13/6.
You will simply have to multiply the time spent walking, 13/6 hours, by the average distance traveled on an hourly basis, 15/4 km/h.
(13*15)/(4*6) = 195/24 = 8,125 km
