A car has a uniform velocity of 108km/h.how far does it travel in 1/2minutes

First, we need to convert the velocity to meters per second so that we can use it for further calculations.

108 km/h = 30 m/s (approx)

Now, we can use the formula:

distance = velocity x time

Here, the time is given as 1/2 minutes or 30 seconds. So,

distance = 30 m/s x 30 s

distance = 900 meters

Therefore, the car travels 900 meters in 1/2 minutes at a uniform velocity of 108 km/h.
