S = 12km t = 11.30 - 07.00 - (4 × 30 mnt) = 04.30 - 02.00 = 02.30 = 2,5 jam v = s / t = 12 / 2,5 = 4,8 km/jam

S = 12km t = 11.30 - 07.00 - (4 × 30 mnt) = 04.30 - 02.00 = 02.30 = 2,5 jam v = s / t = 12 / 2,5 = 4,8 km/jam
t = 11.30 - 07.00 - (4 × 30 mnt)
= 04.30 - 02.00
= 02.30
= 2,5 jam
v = s / t = 12 / 2,5 = 4,8 km/jam
t = 11.30 - 07.00 - (4 × 30 mnt)
= 04.30 - 02.00
= 02.30
= 2,5 jam
v = s / t = 12 / 2,5 = 4,8 km/jam
