Question

If sound travels 19.8km in 1minutes, how far does it travel in 1sec​

Answer 1

Divide 19.8 by 60 and you should get an answer of 0.33

Answer 2

`(1)/(3)` km/s or 0.3333333 km/s (you can round to whatever value you need to)

Explanation:

We can write the rate at which sound travels as the fraction
`(19.8)/(1)` km/min

As there are 60 seconds in a minute, we can replace the 1 min with 60 seconds in this fraction
`(19.8)/(60)` km/s.

When reduces, this fraction gives us:
`(1)/(3)` km/s or 0.3333333 km/s (you can round to whatever value you need to)
