Solution

The correct option is B

4.47


Let the aircraft and the submarine be ‘x’ m above and below the tanker respectively. Time taken by sound to reach the aircraft is tair=x340s
Time taken by sound to reach the submarine twater=x1520s
Ratio of the time taken
tairtwater=(x340)(x1520)=1520340=4.47
