To find the time it takes to travel a certain distance at a given speed, you can use the formula:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]
In this case, the distance is 180 miles and the speed is 60 miles per hour.
Plugging the values into the formula:
\[ \text{Time} = \frac{180 \text{ miles}}{60 \text{ miles per hour}} = 3 \text{ hours} \]
Therefore, the answer is:
C) 3 hours
