Answer :
Final answer:
To calculate the number of highway signs during a 16.1-hour road trip, with signs posted every 0.7 hours, divide 16.1 by 0.7 and add one for the final sign, which results in a total of 24 signs.
Explanation:
The student's question addresses how to find the number of highway signs posted on a trip, given the total travel time of the trip and the frequency at which signs are posted. To determine the number of signs, divide the total travel time by the time interval at which signs are posted and add one for the sign at the end of the trip.
Calculating the number of signs involves the following steps:
Divide 16.1 (total hours) by 0.7 (hours between signs).
This gives us approximately 23. Therefore, there are 23 signs before the last one.
Add one more sign for the end of the trip.
Therefore, the total number of signs is 24.
This is an example of an application of division in solving real-world problems related to rates and intervals.
Answer:
23
Step-by-step explanation:
Since one sign is posted every 0.7 hours, divide 16.1 by 0.7 to get 23.
If the question is implying that there was one at the start too the answer is 24.
