Question

Sayyohlar oqim tezligi 2 km/h bo'lgan daryo bo'ylab 72 km suzishlari kerak. Agar ular suzish davomida har biri 80 minutdan 5 marta tanaffus qilsalar, ularning sayohati qancha vaqt davom etgan?​

Answer 1

72km ÷2km/h=36 soat

80minut • 5= 400 minut

400 ÷60= 6 soat 40 minut

36 soat + 6 soat 40 minut= 42 soat 40 minut
