Mert 2 daqiqada 40 sm, Mustafa esa 3 daqiqada 45 sm yura oladi. Ular bir vaqtda bir-biriga qarab harakatlanishdi va 2 soatda uchrashishgan bo'lsa, ular orasida qanday uzunlikdagi masofa bo'lgan?

  1. 4200m
  2. 4,2m
  3. 42m
  4. 420m

📝 Detailed explanation

Mertning tezligi: 40 ÷ 2 = 20 sm/daq. Mustafoning tezligi: 45 ÷ 3 = 15 sm/daq. Yaqinlashish tezligi: 20 + 15 = 35 sm/daq. 2 soat = 120 daqiqa. Jami masofa: 35 · 120 = 4200 sm. Metrga o'girsak: 4200 sm = 42 m.
