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.
