Final answer:
After calculating the police car's total time as 1.9167 hours, we find that the average speed is approximately 24.006 mph. The closest answer option is 25 mph.
Step-by-step explanation:
To calculate the average speed of the police car, we use the formula:
Average speed = total distance / total time
The police car drives 46 miles in 1 hour and 55 minutes. First, we should convert the time to hours as the distance is in miles:
1 hour 55 minutes = 1 hour + 55/60 hour = 1.9167 hours (approximately)
Now, we calculate the average speed:
Average speed = 46 miles / 1.9167 hours = 24.006 mph (approximately)
The closest answer to our calculated average speed is option A, which is 25 mph.
