Question

speed of sound in air is 340ms in water 1360ms find time travel distance1700m by sound in air ,water

Answer 1

use formula,

time = distance /speed

for air medium
time taken by sound = 1700/340
=1700/340 sec
=5 sec

for water medium,

time taken by sound = 1700/1360
=170/136 sec
=10/8 sec
=1.25 sec

Answer 2

time = d/sp.

1. t = 1700/340 ( air)
5 m/s
2. t= 1700/1360
1.25 m/s
