Answer 2

Answer:

The time of their meeting is the LCM of 18 and 12 in minutes.

The time of their meeting is the LCM of 18 and 12 in minutes.Prime factorisation of 18=2×3×3

The time of their meeting is the LCM of 18 and 12 in minutes.Prime factorisation of 18=2×3×3Prime factorisation of 12=2×2×3

The time of their meeting is the LCM of 18 and 12 in minutes.Prime factorisation of 18=2×3×3Prime factorisation of 12=2×2×3Hence, LCM of 18,12=2×3×3×2=36

The time of their meeting is the LCM of 18 and 12 in minutes.Prime factorisation of 18=2×3×3Prime factorisation of 12=2×2×3Hence, LCM of 18,12=2×3×3×2=36Sonia and Ravi meet after 36 minuets...
