The ratio of the time taken by tap A to fill the bathtub to that by tap B is 5: 6. If tap A takes 36 minutes to fill a bathtub, how long would B take to fill the same bathtub?
Given :
The ratio of the time taken by Tap A to fill the bathtub to that taken by Tap B $= 5: 6$.
Time taken by Tap A $= 36$ minutes.
To do :
We have to find the time taken by tap B to fill the bathtub.
Solution :
Let the time taken by Tap B be x.
$\frac{5}{6} = \frac{36}{x}$
$5(x)=36(6)$
$5x=216$
$x=\frac{216}{5}$
$x=43.20$ minutes
Time taken by Tap B is 43 minutes 12 seconds.
