a round in 18 minutes. If they both

started at the same place and time

and go in the same direction, after

how many minutes will they meet

again at the starting point?

\huge \mathsf \blue{Given}

  • First rider takes 12 minutes to complete a round.
  • Second rider takes 18 minutes to complete a round.


\huge \mathsf \blue{To\: Find}

After how many minutes will they meet

again at the starting point?

Take the LCM of 12 and 18

12 = 2 × 2 × 3

18 = 2 × 3 × 3

Thus, the LCM of 12 and 18 is 36.

So they will meet after 36 minutes again at the starting point.
