Answer 2

Calculation of Motorcycle Speed

To calculate the speed of the motorcyclist, we can use the formula:

Speed = Distance / Time

In the given scenario, the motorcyclist traveled 2 km in 20 minutes and then traveled an additional 6 km in the next 20 minutes.

Let's calculate the speed for each segment:

1. First 20 minutes: - Distance: 2 km - Time: 20 minutes

Using the formula, we can calculate the speed:

Speed = 2 km / 20 min = 0.1 km/min

2. Next 20 minutes: - Distance: 6 km - Time: 20 minutes

Using the formula, we can calculate the speed:

Speed = 6 km / 20 min = 0.3 km/min

Therefore, the motorcyclist traveled at a speed of 0.1 km/min for the first 20 minutes and then increased their speed to 0.3 km/min for the next 20 minutes.

Please note that the given information does not provide the total distance traveled or the average speed over the entire journey. We have only calculated the speed for the two given time intervals.
