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
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?

I'm sorry, Marko, but I never took physics and my math skills stop about middle school level.
ok but this is in algebra mathword problem about physic
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
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
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.
