Question

Во время парада ко дню победы колонна военных машин проехала по мосту длина которого 700 м за 4 минуты а мимо ветерана отдыхавшего на лавочке за 3 минуты какова длина колонны?

Answer 1

Пусть длина колонны х
тогда колонны прошла 700+х метров
пусть скорость у

получаем 2 уравнения

(700+х)/у=4
х/у=3      у=х/3

700+х = 4у = 4х/3
1/3х=700  х=700/3=233 1/3 м

Answer 2

Calculation of the Length of the Column

To calculate the length of the column of military vehicles, we can use the formula:

Length = Speed x Time

Given that the column of military vehicles took 4 minutes to pass a bridge with a length of 700 meters, and it took 3 minutes to pass a veteran sitting on a bench, we can set up the following equations:

700 meters = Speed x 4 minutes Distance passed by the veteran = Speed x 3 minutes

To find the length of the column, we need to determine the speed of the military vehicles. Unfortunately, the search results did not provide any information about the speed of the vehicles or the time it took for the veteran to be passed. Therefore, without this information, it is not possible to calculate the exact length of the column.
