1.	24. A submarine sends out a sonar signal (sound wave) in a direction directly downward.

Answer» aExplanation:SINCE Time for Two way is 2.3 secstherefore for SINGLE way = 1.5secSpeed = 1490m/sDist = Speedtime = 14902.3 = 3427Since the 2(Distance) = 3427 (Since SONAR goes from ship to BOTTOM and then to Ship)Therefore D = 3427/2 = 1713.5 meterHence OPTION (a) = 1700m
