Question

Jonas practices guitar 1 hour a day for 2 years. Bradley practices the guitar 2 hours a day more than Jonas. How many more minutes does Bradley practice the guitar than Jonas over the course of 2 years?

Answer 1

Bradley practice 109500 more minutes than Jonas over the course of 2 years.

Explanation:

Jonas practices guitar 1 hour a day for 2 years.

1 year = 365 days

2 years =
`365 * 2 = 730 days`

1 hour = 60 minutes

So, Jonas practice for 60 minutes in 1 day

Jonas practice for minutes in 365 days =
`365 * 60 =21900 minutes`

Bradley practices the guitar 2 hours a day more than Jonas.

So, Bradley practice the guitar for hours per day = 2+1=3 hours

3 hours = 3 \times 60 = 180 minutes

Bardley practice for minutes per day = 180 minutes

Bardley practice for minutes for 730 days =
`180 * 730 =131400 minutes`

Difference in minutes in 2 years = 131400-21900=109500 minutes

Hence Bradley practice 109500 more minutes than Jonas over the course of 2 years.
