Answer 1

Answer:

Such questions are very tough and are generally answered by few

Answer 2

Explanation:

time taken by the signal ,t=102/2=51s

speed of sound =1531

therefore speed of sound=distance /time

distance =speed×time

=1531×51

=78081

Therefore distance =total distance/2

=78081/2

=39,040.5m
