jika berangkat ke sekolah pukul 06.15 denga kecepatan 60km/jam dan jarak 20km, pukul berapa sampai d sekolah??

v = 60 km/jam
s = 20 km
to = 06.15
t1 = ......???

s = v × t
t = s/v
t = 20 km/60 km/jam
t = 1/3 jam
t = 1/3 × 60 menit
t = 20 menit

t1 = to + t
t1 = 06.15 + 00.20
t1 = 06.35

Jadi sampai di sekolah pukul 06.35

60km/60menit=20km/x
60km/x=60menit.20km
x=60menit.20km/60km
x=20menit
6.15+20menit =6.35 menit
