Question

Два жука одновременно поползли от дерева в противоположных направлениях. Скорость первого 3 см/с второго 5 см/с. Через сколько секунд расстояние между ними будет равно 48 см?

Answer 1

5+3=8см/с- скоровсть удаления жуков
48/8=6 с - через столько между ними было расстояние 48 см 
Ответ: через 6 секунд

Answer 2

Calculating the Distance Between Two Bugs

To calculate the time it takes for the distance between the two bugs to be 48 cm, we can use the formula:

Distance = Speed * Time

The bugs are moving in opposite directions, so we need to consider their relative speed. The relative speed of the bugs is the sum of their individual speeds.

Given: - Speed of the first bug (v1) = 3 cm/s - Speed of the second bug (v2) = 5 cm/s - Distance between the bugs = 48 cm

We can use the formula to find the time it takes for the bugs to be 48 cm apart.

Calculating the Time

Let's denote the time it takes for the bugs to be 48 cm apart as 't'. Using the formula Distance = Speed * Time, we can write the equation:

48 = (3 + 5) * t

Solving for 't':

48 = 8t

t = 48 / 8

t = 6 seconds

So, it will take 6 seconds for the distance between the bugs to be 48 cm.
