Answer:
12
Explanation:
To answer this question, we need to convert 0.6 km to metres and then divide by 50. One kilometre is equal to 1000 metres, so 0.6 km is equal to 600 metres. To find the number of laps in this distance, we divide 600 by 50 and get 12. Therefore, Maddie swam 12 laps in a 50 metre pool.
Hope this helps :)
