Question

Tolong bantu jwb yaaa.. ( soalnya ada digambar, nomer 1 sampai 7 )

Answer 1

1.
jarak = 10 km
t = 30 menit = 0,5 jam
kecepatan = 10 / 0,5 = 20 km/jam

2.
jarak = 6,5 km
t = 15 menit = 0,25 jam
kecepatan = 6,5 / 0,25 = 26 km/jam

3.
kecepatan = 120 km/jam
t = 75 menit = 1,25 jam
jarak = 120 * 1,25 = 150 km

4.
jarak = 45 m
kecepatan = 3 m/jam = 0,05 m/menit
t = 45 / 0.05 = 900 menit

5.
jarak = 180 km
kecepatan = 90 km/jam
pukul = 14.30
t = 180 / 90 = 2 jam
tiba pukul = 14.30 + 2.00 = 16.30

6.
t = 11.00 - 5.30 = 5,5 jam
jarak = 330 km
kecepatan = 330 / 5,5 = 60 km/jam

7.
jarak = 210 km
pukul = 11.30
kecepatan = 60 km/jam
t = 210 / 60 = 3,5 jam
tiba pukul = 11.30 + 3.30 = 15.00
