K = 60 km/jamw = 30 menit = 1/2 jamj = ?j = (k:w) 60 km : 1/2 jam = 30 km  = 30 km/1/2 jam = ... m/s   = 30 km = 30000 m     1/2 jam = 1800 s    = 30000 m : 1800 s   = 16,7 m/s
maaf kalo salah
k = 60 km/jam

w = 30 menit = 1/2 jam

j = ?

j = (k:w) 60 km : 1/2 jam = 30 km

= 30 km/1/2 jam = ... m/s

= 30 km = 30000 m

1/2 jam = 1800 s

= 30000 m : 1800 s

= 16,7 m/s
