Answer :
To find the number of highway signs on the road trip, divide the total travel time by the interval at which signs are posted and add one for the sign at the end. For a 19.6-hour trip with signs every 0.07 hours, there would be 281 signs.
To calculate the number of highway signs you would encounter on a road trip, you divide the total travel time by the frequency at which the signs are posted. In this case, the total travel time is 19.6 hours, and the signs are posted every 0.07 hours. We calculate the number of signs by using the formula:
Number of signs = Total travel time / Time between signs
Number of signs = 19.6 hours / (0.07 hours/sign)
Number of signs = 280 signs
Since there is also a sign at the end of the road trip, we need to include this in our total count, which brings the total number of highway signs to 281.
Answer:
280 highway signs
Step-by-step explanation:
The total length of a road trip was 19.6 hours
Highway signs are posted every 0.07 hours
To find: Number of highway signs
The number of highway signs = total length of a road trip/highway signs
Substituting the values we get,
number of highway signs = 19.6/0.07 = 280
Thus there are 280 highway signs
