Question

There is a circular path around a sports field. Sonia takes 18 minutes to drive one round
of the field, while Ravi takes 12 minutes for the same. Suppose they both start at the
Nume point and at the same time, and go in the same direction. After how many minutes
will they meet again at the starting point?
help me with this question . please​

Answer 1

$\red{\textbf{Answer :-36}}$

Step-by-step explanation:

They will be meet again after LCM of both values at the starting point.

To get the LCM we have to factorize the number.

18 = 2 × 3 × 3

12 = 2 × 2 × 3

LCM = 2 × 2 × 3 × 3 = 36

Therefore, they will meet together at the starting point after 36 minutes.

$\red{\textbf{More information:-}}$

• For two integers a and b, denoted LCM(a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b.

• $\textbf{Least Common Multiple:-}$ the least common multiple is the smallest of the common multiples.
