Show answer
Correct Option: C
Explanation:

To solve this question, the user needs to know the formula for average speed, which is:

Average speed = total distance traveled / total time taken

The problem gives us the distance traveled, which is 180 miles, and the time taken, which is 3 hours and 45 minutes (the difference between 11.57 am and 8.12 am). However, we need to convert the time taken to hours and decimals of an hour (since average speed is typically measured in miles per hour).

Converting 3 hours and 45 minutes to hours and decimals of an hour:

3 hours + (45 minutes / 60 minutes per hour) = 3.75 hours

Now, we can use the formula to calculate the average speed:

Average speed = 180 miles / 3.75 hours ≈ 48 miles per hour

Therefore, the correct answer is:

The Answer is: C. 48
