Question

Together, two wildlife refuge tour guides each lead ten 45-minute tours each day. The wildlife refuge needs to calculate the person-hours for the tours to allocate enough money in their budget to pay the tour guides. What is the number of person- hours per day for the tours? A. 15 B. 600 C.300 D.30

Answer 1

First, let's calculate the minutes that each tour guide works in a day.

They lead ten 45 minute tours each day. Thereby,

`10*45=450`

Each tour guide works 450 minutes per day

This means that, in total, 900 person-minutes are needed every day.

Now, let's convert this to hours using a rule of three:

This way,

`\begin{gathered} x=(900*1)/(60) \\ \rightarrow x=15 \end{gathered}`

The number of person- hours per day for the tours is 15 (Ans: A)
