Anika's sister goes to music class on Monday, Wednesday and Friday. Each class is for 50 minutes. How much time did Anika's sister practise music in her class in 3 weeks

1 Answer

Number of classes in one week = 3 (Monday, Wednesday, Friday)
Duration of each class = 50 minutes
Number of minutes in one week = 50 * 3 = 150 minutes
Number of minutes in 3 weeks = 150 * 3 = 450 minutes
1 hour = 60 minutes
450 minutes = 7 Hours and 30 minutes
Total time Anika's sister practised music in her class in 3 weeks = 7 Hours and 30 minutes
