This is a question of speed , distance and time which can be solved by using the formula -
Speed = Distance/Time
As, sound signal sent by one boat reaches the other boat .
Here, Distance between two observers = 4.5 km
= (4.5 * 1000) metre
= 4500 metre
Total time taken by sound signal to reach other = 3 sec
According to the formula-
Speed of sound in water = Distance between two observers/Total time taken
= (4500 m)/(3 sec)
= 1500 m/sec
