On a cold day, when the wind blows, it feels colder than it actually is outside. The temperature you feel is called the wind chill temperature.

The table below shows values of the function $W(S)\text{,}$ which calculates the wind chill temperature when it is $40$ degrees Fahrenheit outside, and the wind is blowing at $S$ miles per hour.

$S$	$W(S)$
$0$	$40$
$10$	$34$
$20$	$30$
$30$	$28$
$40$	$27$
$50$	$26$
$60$	$25$

Which pair of statements is true?

$W(26)=50$ and $W^{-1}(60)=25$
$W(40)=27$ and $W^{-1}(30)=20$
