Mapel : MatematikaBab : Kecepatan/Jarak/Waktu
07.45 ----> 15.40
-----> 08.00 ----->15.00 = 55 menit
75 - 55 = 20 menit
08.00 -----> 14.40 = 6 Jam 40 menit
t = 6 Jam 40 menit
t = 6(60) + 40 = 400 menit = 6 2/3 Jam
s = 320 km
V = s/t
V = 320/6 2/3
V = 320/20/3
V = 320 × 3/20
V = 48 km/Jam

Verified answer
Jarak = 320 kmwaktu = 15.40 -07.45 = 07.55 -75 menit = 6.40 =6 2/3 jam
keceptn = jrk / waktu = 320 : 6 2/3
=320 : 20/3
=320 x 3/20
=48 km /jam
