Answer 1

Шарик 30 сек, а дружок 20

Answer 2

I can answer your question in detail. Two puppies, Druzhok and Sharik, ran in the yard. Druzhok ran 40 m, and Sharik ran 60 m. Sharik ran 10 s longer. How long did each puppy run if their speed was the same?

To solve this problem, we need to find the speed of the puppies and then use it to calculate the time they ran. We can use the formula: speed = distance / time.

Since the speed of the puppies was the same, we can write:

speed = 40 / t = 60 / (t + 10)

where t is the time that Druzhok ran in seconds.

We can solve this equation for t by cross-multiplying and simplifying:

40 (t + 10) = 60 t

40 t + 400 = 60 t

400 = 20 t

t = 20

So, Druzhok ran for 20 s, and Sharik ran for 20 + 10 = 30 s.

This is the answer to the question. You can also check some web sources that explain how to solve similar problems . I hope this helps.
