Question

Два экскаватора вырыли котлован за 24 дня. первый экскаватор мог бы выполнить эту работу в 1,5 раза быстрее, чем в торой. за сколько дней первый экскаватор мог бы выполнить эту работу?

Answer 1

Пусть за х дней второй
тогда за 1,5х дней второй
вместе за 24 дня т. е.
1,5х +Х=24
2,5х=24
Х=9,6
т. е. округляем второй за 10 дней
24-10=14 за дней первый

Answer 2

Calculation of Days for Excavator Work

To determine the number of days it would take for the first excavator to complete the work, we can set up a proportion based on the given information.

Let's assume that the second excavator takes 24 days to complete the work. According to the information provided, the first excavator can complete the work 1.5 times faster than the second excavator.

Let's represent the number of days it takes for the first excavator to complete the work as x.

The proportion can be set up as follows:

24 / x = 1.5

To solve for x, we can cross-multiply and then divide:

24 * 1.5 = x

x = 36

Therefore, the first excavator could complete the work in 36 days.
