at 20 degree C the speed of sound in air is 344 m/s. This is 1.117 m/s slower than the speed of sound in water.

write and solve an equation to find the speed of sound in water.

i started writeing this but im not sure how to do this:

344 - s = 344

im not sure how to do this?

can you check : is this righ:

s- 1.117 = 3.44

s-1.117 + 1.117 = 3.44 +1.117

s-0 = 4.557

s= 4.557

4.557 - 1.117 = 3.44

3.44 = 3.44

I'm sorry, Marko, but I never took physics and my math skills stop about middle school level.

You must reside in the part of the world that uses a comma as a decimal point, and vice versa. The speed of sound is water is 1,117 m/s faster than it is in air. (One thousand, one hundred seventeen)

If s is the speed in water,

s = 344 + 1117.

s = 1461 m/s

sorry i mistyped

so can i write it out like this:

s - 1,117 344

s - 1,117 + 1,117 = 344 + 1,117

s-0 = 1461

s=1,461

check; s - 1117 = 344

1461 - 1117 = 344

No, that is all wrong.

I suggest you look again at the way I did it.
