Question

Муха за 30с пролетает 18м. Сколько метров проползёт за это же время гусеница, если её скорость составляет 2|9 скорости мухи? Для решения задачи вырази скорость мухи в метрах в минуту.

Answer 1

за 30 сек муха пролетает 18 метров, значит за минуту она пролетает 18*2=36 метров. Ее скорость 36 м/мин.

Скорость гусеницы всего 2/9 скорости мухи, поэтому скорость гусеницы находится 36/9*2=4*2=8 м/мин

гусеница ползла 30 сек, т.е. 8*1/2=4м проползет гусеница за 30 сек.


Ответ: гусеница проползла 4 метра

Answer 2

Calculation of the Distance Covered by the Caterpillar

To solve this problem, we need to find the distance covered by the caterpillar in the same amount of time it takes for the fly to cover 18 meters.

Given that the fly covers 18 meters in 30 seconds, we can calculate its speed in meters per second by dividing the distance by the time:

Fly's speed = Distance / Time = 18 meters / 30 seconds = 0.6 meters per second.

To find the distance covered by the caterpillar in the same time, we need to express the fly's speed in meters per minute.

Since there are 60 seconds in a minute, we can convert the fly's speed from meters per second to meters per minute by multiplying it by 60:

Fly's speed in meters per minute = Fly's speed in meters per second * 60 = 0.6 meters per second * 60 = 36 meters per minute.

Now, we can calculate the distance covered by the caterpillar using the ratio of the caterpillar's speed to the fly's speed.

Given that the caterpillar's speed is 2/9 of the fly's speed, we can express the caterpillar's speed as a fraction of the fly's speed:

Caterpillar's speed = (2/9) * Fly's speed = (2/9) * 36 meters per minute.

To find the distance covered by the caterpillar, we can multiply its speed by the time taken by the fly to cover 18 meters:

Distance covered by the caterpillar = Caterpillar's speed * Time taken by the fly to cover 18 meters.

Substituting the values, we get:

Distance covered by the caterpillar = (2/9) * 36 meters per minute * 30 seconds.

Now, let's calculate the distance covered by the caterpillar:

Distance covered by the caterpillar = (2/9) * 36 * 30 meters.

Calculating this expression, we find that the caterpillar covers 240 meters in the same amount of time it takes for the fly to cover 18 meters.

Therefore, the caterpillar will crawl a distance of 240 meters in the same time it takes for the fly to fly 18 meters.
