Question

You ride your bike 22 miles and then get a flat tire! You turn around and walk the bike 4 miles before your mom is able to pick you up. How far are you from the house when your mom picks you up?

Answer 1

18 miles away from home

Explanation:

This question requires you to know about displacement. Since you rode 22 miles from home, you are 22 miles away from home, obviously. Now, you walk BACK 4 miles, so take 4 away from 22 and you get 18. This means that your displacement from home is 18 miles. Interestingly, you traveled 26 miles before your mom picked you up, but the question asks for the displacement, and not the distance traveled overall.
