Answer 2

Calculating Average Speed of the Motorcyclist

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

Average Speed = Total Distance / Total Time

Given: - Distance covered in the first 5 minutes = 3 km - Distance covered in the next 10 minutes = 9 km

We can calculate the total distance and total time to find the average speed.

Total Distance = 3 km + 9 km = 12 km

Total Time = 5 minutes + 10 minutes = 15 minutes = 0.25 hours

Now, we can use the formula to find the average speed:

Average Speed = 12 km / 0.25 hours = 48 km/h

So, the motorcyclist's average speed for the entire journey is 48 km/h.
