Answer:
To find out how long it took for the round to travel 2,000 m, we can use the formula:
time = distance / speed
In this case, the distance is 2,000 m and the speed is 500 m/s. So we can plug in these values:
time = 2000 m / 500 m/s
time = 4 seconds
So the round took 4 seconds to travel 2,000m.
