Final answer:
The courier will take 1 minute to travel 0.25 miles.
Step-by-step explanation:
To calculate how many minutes it will take for the courier to travel 0.25 miles, we can use the formula:
Time = Distance / Speed
Given that the speed of the courier is 15 miles per hour and the distance is 0.25 miles, we can substitute these values into the formula:
Time = 0.25 miles / 15 miles per hour
Converting 15 miles per hour to miles per minute:
15 miles per hour = 15 miles / 60 minutes = 0.25 miles per minute
Now we can calculate the time it will take:
Time = 0.25 miles / 0.25 miles per minute = 1 minute
