Dzienks za odp i proszę o pisanie jak rozwiązywaliście

Answer 1

70 m/s=70·3600=252000m/h=252000·0,001km/h=252km/h

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

31 m/s=31·3600=111600m/h=111600·0,001=111,6km/h
32m/s=115200m/h=115,2km/h
100 km/h=100000m/h=100000:3600≈27,8m/s

1km=1000m,1h=3600s
510 km/h=510000m/h≈141,7m/s
310 km/h=310000m/h≈86,1m/s
20 m/s=72000m/h=72km/h
78 m/s=78·60=4680m/min=4,68·60=280,8km/h

1s=1/60min

1min=1/60h
