Answer: 2.5 days
Step-by-step explanation:
First we should convert 12 kilometers to meters so that is 12000 meter. Now we know that she runs 12 laps each day and each lap is 400 meters so lets find out how much she runs in one day. 12 laps*400meters= 4800 meters
So an easy way to figure out how many days is to divide 4800 meters she runs each day from the total 12,000 meters she needs to run so 12,000/400=2.5.
It will take kali a total of 2.5 ( two and a half days) to run 12000 meters or 12 kilometers
