Answer 2

Step-by-step explanation:

It means we have to find the LCM to identify the time when they will meet together.

LCM,

$8 = {2}^{3}$

$10 = 2 \times 5$

$12 = {2}^{2} \times 3$

$14 = 2 \times 7$

$The \: LCM \: of \: 8,10,12,14 = {2}^{3} \times 5 \times 7 \times 3$

$840$

Hence they will meet after 840 minutes or 14 hours
