25m/s (km/h) = 25 * (1/1000 : 1/3600) km/h = 90km/h
1500m/min (km/h) = 1500 * ( 1/1000 : 1/60 ) km/h = 90 km/h
1500m/min (km/h) = 1500 * ( 1/1000 : 1/60 ) km/h = 90 km/h
25 m/s = 25 * 1/1000 / 1/3600 km/h = 25 * 1/1000 * 3600 km/h = 90 km/h
1500m/min = 1500 * 1/1000 / 1/60 km/h = 1500 * 1/1000 * 60 km/h = 90 km/h
1500m/min = 1500 * 1/1000 / 1/60 km/h = 1500 * 1/1000 * 60 km/h = 90 km/h
