AT 8:00 AM you leave home and walk 0.5 km to a friend's house. At 11:30 AM you return home, then travel by car to the mall, which is 10 km away, and arrive at 11:45 AM. What is the total distance traveled?

11km

Explanation:

The total distance travelled is the sum of the distance as follows:

- from home to friend's house

- from friend's house back home

- from home to the mall

According to this question;

* I walked from my house to my friend's place and covered 0.5km

* I walked back from my friend's house home in the same 0.5km

* I drove to the mall from my house and covered a distance of 10km

Hence, the total distance covered is 0.5 + 0.5 + 10

= 11km

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.
