1. The girls are cleaning the ground at exactly 6:40 A.M amd finished cleaning at 7:19 A.M
2. The minutes they spend cleaning the school ground. I will solve it by adding 20 minutes and 19 minutes.
3. Addition and Subtraction. First, I minus the 60 minutes to 40 minutes, then add the difference to 19 minutes. The minutes the girls spend in cleaning the school ground is 39 minutes.
Solution:
60(no. of minutes in an hour) - 40 = 20
20 + 19 = 39 minutes
Hope it helps! Enjoy Learning!
