Answer 2

Let's calculate the relative speed of two men,

• Relative Speed = 2 km/h + 3 km/h = 5 km/h {since they are in opposite direction we should add their speeds}.

Given that,

• Distance = 6 km

• Speed = 5 km/h

• Time = ?

we know, the equation for time,

⇒ Time = Distance / Speed

⇒ Time = 6 km/h / 5 km/h

⇒  Time = 1.2 hours (1.2 hours = 72 minutes).

∴ They both meet after 72 minutes. {For more information see the attachment you will understand}.

Hope this helps you.
