Using proportions, it is found that the mean time between arrivals is of 12 minutes.

  • This question is solved by proportions, using a rule of three.
  • In one hour(60 minutes), 5 trucks arrive, thus what is the time necessary for 1 truck to arrive?

The rule of three is:

5 trucks - 60 minutes

1 truck - x minutes

Applying cross multiplication:

[tex]5x = 60[/tex]

[tex]x = \frac{60}{5}[/tex]

[tex]x = 12[/tex]

The mean time between arrivals is of 12 minutes.
