    The correct answer is the one with 45000 kg*km/hr.

    the formula is p = m*v

    900 * 50/hr giving u 45000

    I know this is the correct answer because i have already turned it in and got a 100%.

    50km/hr can be converted to m/s.

    50 * (1000m/km) * (hr/3600s) = 50 * (1/3.6) = 50/3.6=13.88m/s

    P=mv=900kg*13.88=12492
