Distance = 120 meters
1 second = 3 steps
150 steps = 150/3
   time      = 50 seconds

1. Speed = Distance/ time
            = 150/50
            = 3 m/s

2. 120 meters = 120/1000
                       = 0.12 km
    Time = 50 seconds
             = 50/60*60
             = 0.01 hr
    Speed = Distance / Time
                = 0.12/0.01
                = 12/1
                = 12 km/hr
