1. Problem Description

The problem presents a distance-time graph of Levi's journey on his motorbike. The question asks to calculate the total distance traveled by Levi, in kilometers (km).

2. Solution Steps

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

First, determine the distance traveled away from home. From the graph, Levi traveled from 0 km to 35 km away from home. So the distance traveled away from home is $35 - 0 = 35$ km.

Next, determine the distance traveled back towards home. From the graph, Levi traveled from 35 km to 0 km. So the distance traveled back towards home is $35 - 0 = 35$ km.

To find the total distance traveled, add the distance traveled away from home and the distance traveled back towards home.

Total distance = Distance away from home + Distance back to home

Total distance = $35 + 35 = 70$ km.

3. Final Answer

70 km
