Kali trains for a race by running around a track. Each lap around the track is 400 METERS. She runs 4 KILOMETERS each day. How many laps around the track does Kali run in 3 days?
First step, is to work out how many laps she runs in 1 day. To do this, we divide what she runs in one day, by the length of one lap 4km / 400m TO make this easier, we change to units of one number to make them both the same We will turn them both into meters 4km = 4000m (1km is equal to 1000m, therefore we multiply by 1000)
4000/400 = 10 laps per day
Now we want to find out how many laps are completed in 3 days If 1 day is equal to 10 laps and we want 3 days, we multiply 10 laps by 3 days 10 x 3 = 30 laps
