Answer 2

Calculating the Tourist's Speed on the Last Leg of the Journey

To calculate the tourist's speed on the last leg of the journey, we can use the formula:

Speed = Distance / Time

First, let's calculate the total distance covered and the total time taken for the entire journey.

1. Calculating Total Distance: - Distance covered in the first 2 hours at 5 km/h: 2 hours * 5 km/h = 10 km - Distance covered in the next 2 hours at 4 km/h: 2 hours * 4 km/h = 8 km - Total distance covered in the first 4 hours: 10 km + 8 km = 18 km - Remaining distance covered in the last 3 hours: 27 km - 18 km = 9 km

2. Calculating Total Time Taken: - Total time taken for the first 4 hours: 4 hours - Remaining time taken in the last 3 hours: 3 hours

3. Calculating Speed on the Last Leg: - Speed = Distance / Time - Speed = 9 km / 3 hours = 3 km/h

Therefore, the tourist's speed on the last leg of the journey was 3 km/h.
