Question

ZAMIEŃ JEDNOSTKE Z M/S NA KM/H
10M/S
50M/S
7,5M/S

Answer 1

1 km = 1000 m
1 m = 0,001 km
1 h = 3600 s
1 s = 1/3600 h

10 m/s = 10 * 0,001km/(1/3600)h = 36 km/h
50 m/s = 50 * 0,001km/(1/3600)h = 180 km/h
7,5 m/s = 7,5 * 0,001km/(1/3600)h = 27 km/h

Answer 2

10m/s = 600m/min = 36 000m/h = 36km/h
50m/s = 3000m/min= 180 000m/h = 180km/h
7,5m/s= 450m/min = 27 000m/h = 27 km/h
