4.Sayohatchi katta yo’ldan km/soat tezlik bilan xarakatlanmoqda. Hozir u 0 nuqtada turibdi. Agar u musbat yo’nalish bo’yicha yursa, uning tezligi musbat, agar manfiy yo’nalish bo’yicha yursa, tezligi manfiy hisoblanadi. е qiymat « 4 soat avval» ekanini bildiradi. soatdan keyin sayohatchi qayerga keladi? Masalani: bo’lganda yeching.
5.Ilhom va Go’zal bir joydan bir vaqtda, bir xil yo’nalishda yo’lga chiqishdi. Ilhomning tezligi km/soat, Go’zalning tezligi km/soat. soatdan keyin ular orasidagi masofa qanday bo’ladi? ekanligini bilgan holda masofani bilan belgilab(kilometrlarda), masala yechish uchun formula tuzing. Formula bo’yicha bo’lsa, ni toping.
