Question

Самат решил две задачи за 35 мин. Первую задачу он решал на 7 мин дольше , чем вторую. Сколько минут Самат решал вторую задачу?

Answer 1

35 мин-7 мин=28 мин (решал обе, если бы решал одинаковое время)
28 мин:2=14 мин (решал вторую)
Ответ: вторую задачу решал 14 минут

Answer 2

Task Solution

Let's solve the problem step by step.

Let's assume that Samat took x minutes to solve the second problem. According to the given information, he took 7 minutes longer to solve the first problem than the second problem. Therefore, the time taken to solve the first problem would be x + 7 minutes.

The total time taken to solve both problems is given as 35 minutes. So we can write the equation:

(x + 7) + x = 35

Simplifying the equation:

2x + 7 = 35

Subtracting 7 from both sides:

2x = 28

Dividing both sides by 2:

x = 14

Therefore, Samat took 14 minutes to solve the second problem.
