Question

. William fills 1/3 of a water bottle in 1/6 of a minute. How much time will it

take him to fill the bottle?

Answer 1

It will take him

`(1)/(2)`

of a minute to fill the bottle.

Explanation:

I'm really not sure this is right but..

we can solve using proportions. Cross-multiply and divide.

`( (1)/(3) of \: a \: water \: bottle)/((1)/(6) minute) \: = ( (3)/(3) of \: a \: water \: bottle)/(x) \\ \\ ( (1)/(6) )/( (1)/(3) ) = ( (1)/(3) x)/( (1)/(3) ) \\ \\ (1)/(2) = x`
