The total length of a road trip was 15 hours. If highway signs are posted every 0.6 hours, including one at the end of the road trip, how many highway signs will there be on the road trip
There will be 25 highway signs on the road trip.
To find this answer, you can divide the total length of the road trip (15 hours) by the time between each highway sign (0.6 hours):
15 รท 0.6 = 25
Don't forget to include the sign at the end of the road trip!
" If highway signs are posted every 0.6 hours"
this makes absolutely no sense.
To find the number of highway signs along the road trip, we need to calculate the total number of intervals between the signs.
First, we need to find how many intervals exist within the 15 hours of the road trip. We can do this by dividing the total length of the trip by the time interval between the signs:
Number of intervals = Total length / Time interval = 15 hours / 0.6 hours = 25 intervals
However, this calculation gives us the number of intervals, not the number of signs. Since there is one sign at the end of the road trip and each interval represents the space between two signs, we need to add one to the number of intervals to get the total number of signs:
Total number of signs = Number of intervals + 1 = 25 intervals + 1 = 26 signs
Therefore, there will be 26 highway signs on the road trip.
