Question

kali ran 10 laps around a track each day. each lap around the track is 400 meters. how many days will it take kail to run a total of 12 kilometers

Answer 1

Hey there!;

* Make the conversions:

1 km * 1000 => 1000 m

1 Km ----------- 1000 m
12 Km --------- ??


12 * 1000 / 1 => 12,000 m

she runs 10 * 400 m = 4000 m

Therefore:

12,000 m / 4000 m => 3 days

hope this helps!
