Answer 2

Calculation of Average Speed

To calculate the average speed of the cyclist for the entire journey, we need to find the total distance traveled and the total time taken.

Let's assume the distance for each lap is the same. Therefore, the total distance traveled is twice the distance of one lap.

Let's calculate the average speed step by step:

1. Calculate the distance for each lap: - For the first lap, the cyclist traveled at a speed of 25 km/h. - For the second lap, the cyclist traveled at a speed of 30 km/h.

2. Calculate the total distance: - Since the distance for each lap is the same, the total distance traveled is twice the distance of one lap.

3. Calculate the total time taken: - To calculate the total time taken, we need to know the time taken for each lap. Unfortunately, the time taken for each lap is not provided in the question. Therefore, we cannot calculate the exact average speed without this information.

Without the time taken for each lap, we cannot determine the average speed of the cyclist for the entire journey.
