Answer :
Answer:
To find the number of highway signs on the road trip, we need to divide the total length of the trip by the time between each sign, including the last one.
First, we need to find out how many signs are posted during the trip. To do this, we can divide the total length of the trip by the time between each sign:
16.2 / 0.6 = 27
So there will be 27 signs posted during the trip, including one at the end.
Therefore, there will be 27 highway signs on the road trip.
