Answer:
3 days
Step-by-step explanation:
Kali runs 10 laps around a track each day, and each lap is 400 meters. So, the first step would be:
10 • 400 = 4,000
That means Kali runs 4,000 meters each day.
Now, there are 1,000 meters in 1 kilometer. This means he runs 4 kilometers each day, and we're trying to get to 12 kilometers.
The final step is to divide. 12/4 = 3
So, it would take 3 days for him to run a total of 12 kilometers.
