Mototsiklchi 1 soatda 40 km yo'l bosdi. Qolgan 2 soatda esa 50 km/soat tezlik bilan yurdi. Uning butun yo'l davomidagi o'rtacha tezligi necha km/soat ga teng?

  1. 40,17
  2. 42,5
  3. 46,66
  4. 52,53

📝 Detailed explanation

Birinchi bosqichda: s₁ = 40 km, t₁ = 1 soat.
Ikkinchi bosqichda: s₂ = v₂·t₂ = 50·2 = 100 km, t₂ = 2 soat.
Umumiy masofa: s = 40 + 100 = 140 km.
Umumiy vaqt: t = 1 + 2 = 3 soat.
O'rtacha tezlik: v = s/t = 140/3 ≈ 46,66 km/soat.
Javob: C) 46,66.
