Question

If half of the starting quantity of a is used up after 56s, calculate the fraction that will be used up after 6.0min.

Answer 1

Answer: The fraction that will be used up after 6.0 min is
`(45)/(14)`

Step-by-step explanation:

In 56 second fraction used =
`(1)/(2)`

In 1 second fraction used will be =
`(1)/(2* 56)`

6.0 min = 360 seconds (1 min = 60 seconds)

In 360 seconds fraction used =
`(1)/(2* 56)* 360=(45)/(14)=3.2142`

The fraction that will be used up after 6.0 min is
`(45)/(14)`
