Question

Zamiana jednostek !
proszę o pomoc :c

a) 38 km/h = ... m/s
b) 126 km/h = ... m/s
c) 0,5 km/h = ... m/s
d) 15 m/s = ... km/h
e) 120 m/s = ... km/h
f) 0,7 m/s = ... km/h

Answer 1

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

a)
38km/h = 38 * 1000m/3600s = 10,(5) m/s = 10,56 m/s
b)
126km/h = 126 * 1000m/3600s = 35 m/s
c)
0,5km/h = 0,5 * 1000m/3600s = 0,138 m/s = 0,14 m/s

d)
15m/s = 15 * 0,001km/(1/3600)h = 54 km/h
e)
120m/s = 120 * 0,001km/(1/3600)h = 432 km/h
f)
0,7m/s = 0,7 * 0,001km/(1/3600)h = 2,52 km/h
