Number of hours Jonas practising, j = 1 hr.
Number of hours Bradley practising, b = 3 hr.
Total minutes of hour Jonas practised :
[tex]T_j = 1\times 365\times 2\times 60\ minutes\\\\T_j = 43800\ minutes[/tex]
Total minutes of hour Bradley practised :
[tex]T_b=(1+2)\times 365\times 2\times 60\ minutes\\\\T_b =131400\ minutes[/tex]
Therefore, Jonas and Bradley practice for 43800 minutes and 131400 minutes respectively.
Hence, this is the required solution.
