Question

129.° За четыре дня похода туристы израсходовали половину запасенных продуктов. На сколько дней им хватит оставшихся про­ дуктов? На сколько дней было запасено продуктов?

Answer 1

Половина продуктов - 1/2 => у них осталось столько же продуктов еще на 4 дня. Всего 4+4=8. На 8 дней было запасено продуктов

Answer 2

Calculation of Remaining Food Supply

To determine how many days the remaining food supply will last, we need to know the initial number of days' worth of food that was stocked and the amount of food consumed in four days.

Let's assume that the tourists initially had enough food to last for "x" days. After four days of the trip, they have consumed half of the stocked food supply.

To find out how many days the remaining food will last, we can set up the following equation:

x/2 = (x - 4)/1

Simplifying the equation, we can solve for "x" to determine the initial number of days' worth of food that was stocked.

x/2 = x - 4

x = 2(x - 4)

x = 2x - 8

8 = x

Therefore, the initial number of days' worth of food that was stocked is 8 days.

Now, let's calculate how many days the remaining food supply will last. Since the tourists have already consumed half of the stocked food supply in four days, they have 4 days worth of food left.

Thus, the remaining food supply will last for 4 days.

Please note that the calculations above are based on the assumption that the rate of food consumption remains constant throughout the trip and that there are no other factors affecting the food supply.
