Question

Koto’s average velocity was 4.5 m/s. She started at her house and traveled 15000 meters north, 5000 meters east, 20000 meters south, and then 5000 meters west.
What was the time of her trip? (There are 60 seconds in 1 minute.)

Answer 1

Answer: 10000s or 167 minutes

Explanation:

speed = distance/time rearranges to give time = distance/speed.

You then just calculate each scenario separately and add the individual times together;

(15000/4.5) + (5000/4.5) + (20000/4.5) + (5000/4.5) = 10000s

you can divide 10000 seconds by 60 to convert it into minutes, then divide it by 60 again turn it into hours
