Question

What part of an hour passes from 1:35 pm to 2:15 pm? Solve

Answer 1

Given:

`\text{From 1:35pm to 2:15pm}`

The difference between both times is;

`2\colon15-1\colon35=40\text{minutes}`

Hence, as a part of an hour, we convert the minutes to hour as a fraction.

`\begin{gathered} 60\text{minutes}=1\text{hour} \\ \text{Hence,} \\ 40\text{minutes}=(40)/(60) \\ =(2)/(3)hr \end{gathered}`

Therefore,

`(2)/(3)\text{ of an hour passes from 1:35pm to 2:15pm}`
