Answer:
23,801 km
Step-by-step explanation:
Here, the given problem,
The distance travelled from home to Qatar = 11,469 km,
The distance travelled from Qatar to Brisbane = 12,332 km,
So, total distance travelled from home to Brisbane = 11469 + 12332
= 23,801 km
Now, making the bar diagram,
Take a grid that shows 11469 and join this with the grid that shows 12332,
We obtain a grid that shows 23801.
