a submarine is diving at a speed of 36.5 fathnoms per minute?

Question

experss this speed in meters per second?
what is this speed in miles per hour
what is this speed in light year per year

can you please show the solutions thanks

Answer 1

Let me fathom that... Hmmm

I think that
1 fathom = 1.8288 meters
V=36.5 fth/min (1min/60s)(1.8288m/1fth)
V=1.11 m/s
you do the rest if
1 fathom = 6 feet
1mi=5280feet
I don't think you want it in parsecs...:)

Answer 2

One fathom = 6 feet
Diving Speed = 36.5 fat./min = 3.65 ft / sec = 2.489 mph
.................................................=======================
One metre = 3.278 ft (or) 3.65 ft = 1.113 Metre
Diving speed = 1.113 m/s
=====================
No of sec. in one year = 365.25 x 24 x 3600
Diving speed in one year = 1.113 x 365.25 x 24 x 3600 m/y
One light year = 3 x 10^8 x 3600 x 24 x 365.25 m
Hence, Diving Speed =
= (1.113x365.25x24x3600) / (3x10^8x3600x24x365.25)
= 3.71 x 10^ -7 LY / year
===================
