Question

Wyraź w metrach na sekundę:

150 km/min
00,07km/s
50km/h
120cm/min

tylko proszę to zróbcie na dziś i z obliczeniami daj najjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj.P.S. dziękuje tym co mi pomogą

Answer 1

150 *1000m/60s= 2500m/s
0,07* 1000m/s= 70 m/s
50*1000m/3600s=13,9 m/s
120*0,01m/60s= 0,02m/s

Answer 2

1km=1000m
1min=60s
1h=3600s
1cm=1/100m
150km/min=(150*1000m)/60s=2500m/s (mnożymy przez 1000m, ponieważ 1km=1000m, dzielimy na 60s, bo 1min=60s)
0,07km/s=(0,07*1000m)/1s=70m/s
50km/h=(50*1000m)/3600s=13,(8)m/s
120cm/min=(120*1/100m)/60s=0.02m/s
