travel in 30 minutes ? »
translate Indonesia
Seseorang melakukan perjalanan dengan kecepatan 50 km per jam. Lalu berapa meter dia bisa
bepergian dalam 30 menit? »
Penjelasan dengan langkah-langkah:
50 km: 2 = 25 km
because 1 hour = 60 minutes then divide by 2 into 30 minutes
if 50 km per hour then divide by 2 into 25
so 30 minutes he can travel 25 km
translate Indonesia
50 km : 2 = 25 km
karena 1 jam = 60 menit maka dibagi 2 menjadi 30 menit
jika 50 km per jam maka dibagi 2 menjadi 25
jadi 30 menit dia bisa melakukan perjalanan 25 km
Jawabannya adalah B. 25 meters
Jawaban:
C, 25.000 meters
Penjelasan dengan langkah-langkah:
30 minutes = ½ hour
50 km/hour x ½ hour = 25 km
25 km x 1.000 = 25.000 meters

<<Diketahui>>
jarak = 450 km.
kecepatan = 15 km lebih cepat dari kecepatan mobil pertama
<<Ditanya>>
kecepatan rata-rata kedua mobil = ....?
<<Penyelesaian>>
[tex]\boxed{Va\times t=Vb(t-1)}\\Va\times t=(Va+15)(t-1)\\=Va\times t-Va+15t-15\\Va=15t-15\\Va\times t=450\\Va=\frac{450}{t}[/tex]
Selanjutnya Kita akan Substitusikan ke Va=15t-15
[tex]15t-15=\frac{450}{t} \\15t^{2} -15=0\rightarrow menbagi~kedua~ruas~dengan~15\\t^{2} -t-30=0\\(t-6)(t+5)=0\\~~~~~~~~~~~~~~t=6~Jam\\Maka.\\Va=\frac{450}{6}\\Va=75\\Vb=75+15\\Vb=90\\Jadi,rata-rata~kecepatan~kedua~mobil\\=\frac{90+75 }{2} \\=\frac{165}{2} \\=82,5\frac{km}{jam}[/tex]
