ANSWER
The time difference between the two tanks is 3.5 - 2 seconds = 1.5 seconds. That is, the sound takes 1.5 seconds to travel between the tanks. The distance between the two tanks is given as 510 meters.
The speed of sound is given as follows.
Speedofsound=
Timetaken
Distancetravelled
=
1.5seconds
510meters
=340m/s
Hence, the speed of the sound is given as 340 m/s.
