Question

Three children are walking. Their steps measure 36 cm,72cm and 90 cm. If they step from a line AB, their steps will fall together again at a line CD. What is the distance between AB and CD?

Answer 1

Concept:

Distance is the sum of an object's movements, regardless of direction. Distance may be defined as the amount of space an item has covered, regardless of its beginning or finishing position. Distance is a scalar amount. The distance of an item can be characterized as the total way gone by an article.

Given:

Here it is given that three children are walking and their steps measure$36 cm,$ $72cm$ and $90 cm$.

Find:

We have to find  If they step from a line $AB$, their steps will fall together again at a line $CD$. What is the distance between $AB$ and $CD$.

Solution:

According to the question,

three children are walking and their steps measure $36 cm,$ $72cm$ and $90 cm$.

the line will be there LCM

LCM of $36$ and $72$ and $90= 360$.

Hence, the distance between $AB$ and $CD$ will be $360cm$.
