Solution

To solve this problem, we need to convert the speed of the bullet from km/hr to m/s because the time is given in seconds and we need to find the distance in meters.

1 km = 1000 m 1 hr = 3600 s

So, 2520 km/hr = 2520 * 1000 m / 3600 s = 700 m/s

The formula to calculate distance is speed * time.

So, the distance = speed * time = 700 m/s * 0.2 s = 140 m

Therefore, the target is 140 meters away from the rifle.
