Question 272632
<br>
The response from tutor @ikleyn shows one way of solving the problem using a proportion.<br>
Here is a different way to use ratios or proportions to solve the problem, which I personally find easier to understand.<br>
The ratio of the two distances on the map is 80:32 = 5:2, so the ratio of the actual distance is in the ratio 5:2.<br>
{{{150(5/2)=750/2=375}}}<br>
ANSWER: 375 km<br>
