    should it be divde by 120?
    physics helped me with this

    if its in a minute then there will be more water flowing therefore it is 60x 42 something = 5 thousand something

    yeah its definetly x120. you can think about it logically.

    first convert speed from metres per second to metres per minute, and you do this by x60.
    so, 2m/sec x60 = 120m/min

    then, the area was 43.86m²

    the question clearly asked for VOLUME (m³) PER minute.

    so it would make sense to do m² MULTIPLIED by m/min = Xm³/min

    this is the only way to get the correct units

    SO:
    43.86 x 120 = 5263.2
    = 5260m³/min

    yeah true, i thought about units straight away and that's the only way u can get it once it's converted to [m^3][M^-1]

    M = minutes
