Using proportions, it is found that it will take them 0.00248548 minutes to do one loop.
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 rule of three is:
60 min - 300 miles
x min - 0.0124274 miles
Applying cross multiplication:
[tex]300x = 60 \times 0.0124274[/tex]
[tex]x = \frac{60 \times 0.0124274}{300}[/tex]
[tex]x = 0.00248548[/tex]
It will take them 0.00248548 minutes to do one loop.
