Question

You spend 51/2hours at the park this week. You spend 210 fewer minutes at the library than you do at park. How many minutes do you spend at the library?

Answer 1

Given:

Time spent at the park =

`\begin{gathered} 5\text{ }(1)/(2)\text{ hours} \\ \end{gathered}`

Convert this time to minutes

`\begin{gathered} \text{Recall that } \\ \text{1 hour = }60\text{ minutes} \\ 5(1)/(2)\text{ hours = 5}(1)/(2)\text{ x 60}=(11)/(2)\text{ x 60 = 330 minutes} \\ \\ \end{gathered}`

Time spent at the library is 210 minutes fewer than that spent at the park.

This implies the time spent at the library is

`\begin{gathered} \text{Time spent at the park minus 210 minutes} \\ =330\text{ minutes - 210 minutes} \\ =120\text{ miutes} \end{gathered}`

The answer is 120 minutes
