Kali run 10 laps around a track each day. each lap around the track is 400 meter. how many days will it takes kali to run a total of 12 kilometer

First, find her rate for the day. Since she runs 10 laps a day, multiply.

400 times 10= 4000

Next, I'll convert kilometers into meters;
12 times 1000=12,000

Divide to find the days:
12,000/4,000=3
It will take 3 days to run a total of 12 kilometers.

The correct answer is $90
