Final answer:
Without the cyclist's average speed, we cannot calculate the distance traveled in 2 hours and 20 minutes. The question cannot be accurately answered with the provided options.
Step-by-step explanation:
The question "A cyclist travels for 2 hours and 20 minutes. How far does he travel?" requires information about the cyclist's average speed to accurately determine the distance traveled. Without this vital piece of information, we cannot calculate the distance. To find the distance, you would normally use the formula distance = speed × time. As the average speed is not provided in this case, we cannot choose any of the provided options (30 km, 35 km, 40 km, or 45 km) as the correct answer.
When dealing with similar problems, you would convert the hours and minutes into hours (2 hours and 20 minutes is equivalent to 2.33 hours) and then multiply by the given average speed. However, since we do not have the average speed, we cannot proceed with the calculation.
