Question: If a car travels 60 km in 1 hour and 30 minutes, what is its average speed in km/h?

Options:

Correct Answer: 45

Solution:

The total time taken is 1.5 hours. Average speed = total distance / total time = 60 km / 1.5 h = 40 km/h.

If a car travels 60 km in 1 hour and 30 minutes, what is its average speed in km/h?

If a car travels 60 km in 1 hour and 30 minutes, what is its average speed in km/h?

Step 1: Convert the time from hours and minutes to just hours. 1 hour and 30 minutes is equal to 1.5 hours.
Step 2: Identify the total distance traveled, which is 60 km.
Step 3: Use the formula for average speed, which is average speed = total distance / total time.
Step 4: Plug in the values: average speed = 60 km / 1.5 hours.
Step 5: Calculate the average speed. 60 divided by 1.5 equals 40.
Step 6: Therefore, the average speed of the car is 40 km/h.
