1.Zamień jednostki: a). 20m/s na km/min b). 140km/h na m/s c). 250m/min na m/s d). 100km/s na m/min
a)
20 m/s = ? km/min
20 m/s = 20 x 0,001km / 1/60min = 1,2 km/min
b)
140 km/h = ? m/s
140 km/h = 140 x 1000m/3600s = 38,88 m/s = 38,9 m/s
c)
250 m/min = ? m/s
250 m/min = 250m/60s = 4,166 m/s = 4,2 m/s
d)
100 km/s = ? m/min
100 km/s = 100 x 1000m / 1/60min = 6 000 000 m/min
