Average speed = total distance travelled/ total time taken

Let x = time for last 12 km

6=24/1.8+x

x = 2.2 hours

Hi, I think the answers are slightly off. I rechecked my work twice because I didn't see my result in the answer choices. Please modify? Thanks so much.

Dear Moderator,
It seems the correct choice is missing from the answers. Correct answer is 2.2. Hope you will do the needful. Thank you.
