J = 315 km W = 5,25 jam K = J:W = 315 : 5,25 = 60 km/jam (C)

J = 315 km W = 5 jam 15 menit = 5 15/60 = 5 1/4 jam K ?
K = J : W = 315 : 5 1/4 = 315 : 21/4 = 315 x 4/21 = 60 km/jam C
W = 5,25 jam
K = J:W = 315 : 5,25 = 60 km/jam (C)
W = 5 jam 15 menit = 5 15/60 = 5 1/4 jam
K ?
K = J : W = 315 : 5 1/4 = 315 : 21/4 = 315 x 4/21 = 60 km/jam C
Semoga membantu. Maaf klo salah
