A van and a bicycle move towards each other. The speed of the van is 80 km per hour, and the speed of the bike is 20 km per hour.

If they started 300 km apart, how long would it take for them to meet?

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 = hr = 3 hour

Hence,

It would take 3 hours to meet.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
