1. Problem Description

The problem asks us to determine the total distance traveled by Levi on his motorbike based on the given distance-time graph. The answer should be in kilometers.

2. Solution Steps

The graph shows Levi's distance from home over time.

From the graph, we can see:

- Levi travels away from home from time 0 to 30 minutes. During this time, the distance increases from 0 km to 35 km. So, the distance traveled away from home is 35 km.

- Levi stays at the same distance from home (35 km) from 30 minutes to 40 minutes. So, he doesn't travel any distance during this time.

- Levi travels back home from 40 minutes to 60 minutes. During this time, the distance from home decreases from 35 km to 0 km. So, the distance traveled back home is 35 km.

The total distance traveled is the sum of the distance traveled away from home and the distance traveled back home.

Total distance = Distance away from home + Distance back home

Total distance = $35 \text{ km} + 35 \text{ km} = 70 \text{ km}$

3. Final Answer

70 km
