Final answer:
To convert the speed from miles per hour (mph) to miles per minute (mi/min), divide the given speed by 60. For a car driving at 180 mph, the speed in miles per minute is 3 mi/min.
Step-by-step explanation:
To convert the speed from miles per hour (mph) to miles per minute (mi/min), we need to divide the given speed by 60.
This is because there are 60 minutes in an hour.
So, dividing 180 mph by 60 gives us 3 miles per minute.
Therefore, the speed of the car in miles per minute is 3 mi/min.
