1.36*10^7
where the 36 repeats so 36363636363636... and so on
Using proportions, it is found that Diego traveled 15 miles in the cross-town cab ride.
<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, for the miles traveled, Diego paid 18.50 - 2.25 = $16.25. Considering the fee of $1.25 per mile, the distance he traveled is given by:
d = 16.25/1.25 = 15.
