Answer:
6 km
Step-by-step explanation:
We are given the following distances:
- AD = 1 km
- BC = 2 km
- BD = 3 km
- AB = 4 km
- CD = 5 km
If we draw these on a number line, we can see that:
This means that C is on the other side of B as A and D.
Using this information, we can add the distances AB and BC to get the distance from A to C:
AC = AB + BC
AC = 4 km + 2 km
AC = 6 km
