Final answer:
To calculate the duration of a trip, divide the total distance by the average speed. For a 240 km trip at an average speed of 60 km/h, the trip will take 4 hours.
Step-by-step explanation:
If you are traveling in a car at an average speed of 60 km/h and the total trip distance is 240 km, you can calculate the duration of the trip using the formula:
Time = Distance / Speed
In this case:
Time = 240 km / 60 km/h = 4 hours
Therefore, the trip will take 4 hours.
