Question

Со стола на стул ползёт жучок М со скоростью3м/мин.В это же время навстречу ползёт второй жучок N со скоростью 4м/мин.Сколько метров проползёт жук !N до места встречи,если расстояние от стола до стола равно 84м?

Answer 1

нужно 4м + 3м и разделить на 84=12 и потом 12 умножить на 4 = 48

Answer 2

Calculation of the Distance Traveled by the Second Beetle (N)

To calculate the distance traveled by the second beetle (N) before they meet, we can use the formula:

Distance = Speed × Time

Let's denote the distance traveled by beetle N as 'x' and the time taken for both beetles to meet as 't'.

The first beetle (M) is crawling towards the second beetle (N) at a speed of 3 m/min, and the second beetle (N) is crawling towards the first beetle (M) at a speed of 4 m/min.

Since both beetles are crawling towards each other, their combined speed is the sum of their individual speeds, which is 3 m/min + 4 m/min = 7 m/min.

We know that the total distance between the two beetles is 84 m.

Using the formula mentioned above, we can write the equation:

x = 7t

Since both beetles are crawling towards each other, the time taken for them to meet is the same for both beetles. Therefore, we can write:

84 = 7t

Solving this equation for 't', we find:

t = 84/7 = 12 minutes

Now, we can substitute the value of 't' back into the equation to find the distance traveled by beetle N:

x = 7t = 7 × 12 = 84 meters

Therefore, the second beetle (N) will crawl a distance of 84 meters before they meet the first beetle (M).
