Answer:
You would expect to wait 20 minutes if the line was 50 meters long.
Step-by-step explanation:
This question can be solved using a rule of three.
The line of people waiting was 100 meters, and the wait was 40 minutes. How long the wait would have been if the line was of 50 meters?
100m - 40 min
50m - x min
[tex]100x = 50*40[/tex]
[tex]x = \frac{50*40}{100}[/tex]
[tex]x = 20[/tex]
You would expect to wait 20 minutes if the line was 50 meters long.
