to the 173 kmn marker.

the 257 km märker?
Answer in units of km.
How far has he traveled?
Answer in units of km.

Hey there!

He starts from km 257.

Then he travels to km 133.

Finally, he travels to km 173.

His displacement is 257-173, or 84 km.

He traveled 164 km. (Note that distance traveled and displacement are not the same thing.)

Let me know if this helps :)

does anyone know or what?
