Jarak 5 km jika ditempuh dalam waktu 20 menit menggunakan kecepatan rata-rata ..
Answer (4)
I t ′ s n o n e o f t h ose .
d = ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 ⇐ D i s t an ce F or m u l a A ( x 1 ; y 1 ) ; B ( x 2 ; y 2 ) ⇒ d = ∣ A B ∣
As it stands, it's none of those. I believe you were going for the distance formula but copied it wrong.
The formula d = ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2 represents the Distance Formula , used to calculate the straight-line distance between two points on a coordinate plane. It is derived from the Pythagorean theorem, reflecting the difference in x and y coordinates. The correct multiple-choice option is C. Distance Formula .

Jawaban:Diketahui (Dik) :- Jarak (s) = 5 km - Waktu (t) = 20 menit Ditanya (Dit) :Kecepatan rata-rata (v) dalam km/jam Jawab :1. Konversi waktu ke jam :[tex] \( t = 20 \text{ menit} = \frac{20}{60} \text{ jam} = \frac{1}{3} \text{ jam} \) [/tex](karena 1 jam = 60 menit)2. Rumus kecepatan rata-rata :[tex]\( v = \frac{s}{t} \)[/tex]3. Substitusi nilai : [tex]\( v = \frac{5 \text{ km}}{\frac{1}{3} \text{ jam}} = 5 \times 3 = 15 \text{ km/jam} \)[/tex] Hasil :Kecepatan rata-ratanya adalah 15 km/jamKesimpulan Jadi dalam jarak 5 km ditempuh dalam waktu 20 menit, kecepatan rata-rata nya adalah 15 km/jam
