Hyperloop, a new mode of travel, aims to reach a speed of 170 m/s . This is 50% less than the speed of sound.

What is the speed of sound?
Please help

Answer 1

The speed of sound is
`340\ m/s`

Explanation:

Let

x-----> the speed of sound

we know that

`50\%=50/100=0.50`

so

`0.50x=170`

solve for x

`x=170/0.50=340\ m/s`
