Tons = 2500 kg, 40 mm = 4 cm, 3 kg = 3000 grams, 45 minutes = hour, 300 meters = kilometers, hour = 150 minutes, yuan = 35 jiao, 25 meters = 2500 cm, 15 kilometers = 15000 meters, 1 kg = 500 grams.

1 km-h = m-second.

30 m-seconds = 108 km-h.

72 km/h = 20 m/s.

1 km-h = m-second.

30 m-seconds = 108 km-h.

72 km/h = 20 m/s.

Upstairs is the right solution.
