2 h 35 min = ? min
2 h = 2 × 60 min = 120 min
2 h 35 min = 120 min + 35 min = 155 min
***
1 h 10 min = ? min
1 h = 60 min
1 h 10 min = 60 min + 10 min = 70 min
***
2 h 41 min = ? min
2 h = 2 × 60 min = 120 min
2 h 41 min = 120 min + 41 min = 161 min
***
1 h 57 min = ? min
1 h = 60 min
1 h 57 min = 60 min + 57 min = 117 min
***
3 h 20 min = ? min
3 h = 3 × 60 min = 180 min
3 h 20 min = 180 min + 20 min = 200 min

4 h 10 min = [tex]?[/tex] min
4 h = 4 × 60 min = 240 min
4 h 10 min = 240 min + 10 min = 250 min
