Well, on January 19th, it was 6cm high so they are asking how many days it takes to grow 5cm (as 11 - 6 = 5). This means we need to do the height divided by 0.2 to get the number of days. This would be 5/0.2 which is 25 days. 25 days after January the 19th is February 13th which gives us our answer
