Question

Joey fills 1/5 of a toffee box in 1/25 of a

minute. How much time will he take to fill a
toffee box?

Answer 1

1/25 of a minute is 2,4 secs.

1/5 = 2,4s
5/5 = 12 secs

Answer 2

12 seconds will be needed to fill the toffee box.

Explanation:

Joey takes the time to fill
`(1)/(5)` of a box =
`(1)/(25)` of a minute.

`(1)/(25)` of a minute =
`(1)/(25)* 60` seconds

= 2.4 seconds

Now we will use unitary method to get the time to fill a toffee box.

∵
`(1)/(5)` box is filled in the duration = 2.4 seconds

∴ A box can be filled in the time =
`(2.4)/((1)/(5) )`

= 2.4×5

= 12 seconds

Therefore, 12 seconds will be needed to fill the toffee box.
