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

Step-by-step explanation:

Jonas practices guitar 1 hour a day for 2 years.

1 year = 365 days

2 years =

1 hour = 60 minutes

So, Jonas practice for 60 minutes in 1 day

Jonas practice for minutes in 365 days =

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 =

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

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