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.
