a jogger runs 11 km for 2 hours. at this rate, how far will he jog in 30 minutes?

Maaf ya aku ga bisa jawab pake b inggris
Dik : 11 km = 2 jam (2 × 60 = 120 menit)
Dit : 30 menit = ... km?
Jawab :
Perbandingan Senilai
11 = 120
x = 30

Kalikan silang
11 × 30 = 120 × x
330 = 120x
x = 330/120
x = 2,75 km (dibulatkan menjadi 2,8 km)

s1 = 11 km
t1 = 2 jam = 120 menit

t2 = 30 menit
s2 = ....?

s1/t1 = s2/t2
11/120 = s2/30
s2 = 11/120 × 30
s2 = 2,75 km

Jadi dia berlari sejauh 2,75 km
