Final answer:
The average speed of the bus is 24 mph, calculated by dividing the distance of 36 miles by the total travel time of 1.5 hours.
Step-by-step explanation:
To calculate the average speed of the bus in mph, we need to divide the total distance traveled by the total time taken for the trip. The distance traveled by the bus is 36 miles, and the time taken is 1 hour and 30 minutes. First, we convert the time into hours, which is 1.5 hours (since 30 minutes is half an hour). Now, we can calculate the average speed using the formula:
Average Speed = Total Distance ÷ Total Time
Plugging in the numbers, we get:
Average Speed = 36 miles ÷ 1.5 hours
Average Speed = 24 mph (to 1 decimal place).
