Question

One whale fish says something to its friend 175 km away. How long will it be before the friend can hear this? (Speed of sound in water=1531m/s

Answer 1

From question,

Distance (s) = 175 km = 175000 m

Speed in water (v) = 1531 m/s

Time (t) = ?

We know that,

2*s = v*t

(2)(175000) = 1531*t

t = 350000/1531= 228 seconds (Approx)

Hope this helps!

Answer 2

Answer:

given,

Distance (d) =175 km =175000m

speed in water (s) = 1531 m/s

time (t)= ?

2d = distance between whale and friend

=350000

t=d/s = 350000/1531 = 228 seconds (Approx)

I hope it will help you .
