Final answer:
The cyclist will travel 1 mile in 5 minutes at a constant speed of 12 mph.
Step-by-step explanation:
To find the distance traveled in 5 minutes at a constant speed of 12 mph, we need to convert the speed to miles per minute. Since there are 60 minutes in an hour, we can divide 12 mph by 60 to get the speed in miles per minute: 12 mph / 60 min = 0.2 miles per minute.
Now, we can multiply the speed in miles per minute by the time of 5 minutes: 0.2 miles per minute * 5 minutes = 1 mile.
Therefore, the cyclist will travel 1 mile in 5 minutes at a constant speed of 12 mph.
