Answer:
Time taken, t = 4.5 seconds
Step-by-step explanation:
Speed of the bullet, v = 720 m/s
Distance to be covered by the target, d = 3240 m
Let t is the time required for the bullet to strike a target. The time taken is calculated as :


t = 4.5 seconds
So, the time required for the bullet to strike a target is 4.5 seconds. Hence, this is the required solution.
