Using proportions, it is found that it will take them 0.00248548 minutes to do one loop.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, according to their speed, in 60 minutes, they drive 300 miles. In how many minutes will they drive 20 m = 0,0124274 miles?
The <em>rule of three</em> is:
60 min - 300 miles
x min - 0.0124274 miles
Applying cross multiplication:



It will take them 0.00248548 minutes to do one loop.

THE SLOPE IS 1 AND THE Y INTERCEPT IS -3, the x is equal to 1, and the -3 is in the place of the y intercept so your answer would be A.
-3 x -26 = 78
meaning the answer is D.
The reason the answer is D, is because two negatives when multiplied or divided become positive. Only when multiplied or divided does this occur.
