The total length of a road trip was 18.9 hours. If highway signs are posted every 0.07 hours, including one at the end of the road trip, how many highway signs will there be on the road trip?

Answer :

Final answer:

To calculate the number of highway signs on the road trip, divide the total length of the road trip by the interval between each highway sign. In this case, there will be 270 highway signs on the road trip.

Explanation:

To calculate the number of highway signs on the road trip, we need to divide the total length of the road trip by the interval between each highway sign. In this case, the total length of the road trip is 18.9 hours and the interval between each highway sign is 0.07 hours. We can use the formula:

Number of highway signs = Total length of road trip / Interval between signs

Number of highway signs = 18.9 / 0.07 = 270

Therefore, there will be 270 highways signs on the road trip.
