Question

Гусеница сидела на дереве на высоте 8м 60см от земли.Она поползла вниз и ползла 5мин со скоростью 75см/мин..Пролетавший жук столкнул ее.Гусеница пролетела 2м зацепилась за ветку.На какой высоте она оказалась?

Answer 1

75*5=3м 75см она проползла за 5 минут

8м60см-3м75см-2м=4м83см 

Answer 2

75*5=275 см  ... 

860-375= 485 см 

485 - 200 = 285 см .. ответ 285 см над землёй

Answer 3

Problem Analysis

To solve this problem, we need to determine the final height of the caterpillar after it crawls down the tree and is knocked back by the passing beetle. We are given the initial height of the caterpillar, the time it takes to crawl down, and its crawling speed. We also know that it flies 2 meters after being knocked back.

Solution

Let's break down the problem step by step:

1. Calculate the distance the caterpillar crawls down the tree. 2. Determine the time it takes for the caterpillar to crawl down. 3. Calculate the distance the caterpillar crawls horizontally after being knocked back. 4. Determine the final height of the caterpillar.

Step 1: Calculate the distance the caterpillar crawls down the tree.

The caterpillar crawls down from a height of 8 meters 60 centimeters. To calculate the distance it crawls down, we need to convert the height to centimeters and subtract the final height from the initial height.

Initial height = 8 meters 60 centimeters = 860 centimeters Final height = 0 centimeters

Distance crawled down = Initial height - Final height = 860 cm - 0 cm = 860 cm

Step 2: Determine the time it takes for the caterpillar to crawl down.

The caterpillar crawls down for
