It would take 3 hours to meet.

Step-by-step explanation:

Given,

The velocity of van (a) = 80 km/hr

Velocity if bike(b) = 20 km/hr

Distance between them = 300 km

To find the time they will meet.

Formula

Since, they are moving towards each other the relative velocity = (a+b) km/hr

Distance = velocity × Time

Now,

The relative velocity = (80+20) km/hr = 100 km/hr

So,

Time = [tex]\frac{300}{100}[/tex] hr = 3 hour

Hence,

It would take 3 hours to meet.
