1 of 2

Determine the total number of minutes for four days.

$\begin{gather*} 45 \cdot 4 = 180 \end{gather*}$

Determine the new average time in minutes with the given time on the fifth day. Let $m$ be the new average time.

\begin{align*} (180 + 60) \div 5 &= m && \text{Write an equation}\\ 240 \div 5 &= m && \text{Perform operation inside the parentheses}\\ 48 &= m && \text{Divide the values} \end{align*}

The new average time is 48 minutes per day.
