Verified answer
Mencari Kecepatan = Jarak : WaktuJ = 10 + 45 + 15 = 70 km
W = 5 + 10 + 15 = 30 menit = 0,5 jam
Lalu 70 km : 0,5 jam = 35 km/jam (B)
Translate english
Looking for speed = Distance : Time
D = 10 + 45 + 15 = 70 km
T = 5 + 10 + 15 = 30 minutes = 0,5 Hours
then 70 km : 0,5 Hours = 35 km/h (B)
Semoga membantu.....
#maaf jika ada kesalahan
= (10+45+15)km / (5+10+15)minutes
= 70km / 30minutes
= 70km×30/60 hour
= 35km / hour ( B )
