Hey Mate,
Here's your answer
_____________________
=> Mass of brick = 5 kg
=> Time 1 = 3 min
=> Time 2 = 5 min
_____________________
ATQ,
=> Power = Work / Time
=> Converting time to sec
=> Time 1 = 3 × 60 = 180 sec
=> Time 2 = 5 × 60 = 300 sec
_____________________
Power 1 = 5 / 180
Power 1 = 0.0277777778
Power 2 = 5 / 300
Power 2 = 0.0166666667
_____________________
Clearly we can see that boy 1 has more power than boy 2
