Solution:
Given that,
The total length of a road trip was 17.6 hours
Highway signs are posted every 0.08 hours
To find: Number of highway signs
The number of highway signs is found as:
[tex]\text{Number of highway signs} = \frac{\text{total length of a road trip}}{\text{Highway signs}}[/tex]
Substituting the values we get,
[tex]\text{Number of highway signs} = \frac{17.6}{0.08} = 220[/tex]
Thus there are 220 highway signs
