Speedometer readings for a motorcycle at 12-second intervals are given in the following table: $$\begin{array}{|c|c|c|c|c|c|c|}\hline t\ (\textrm{s}) & 0 & 12 & 24 & 36 & 48 & 60 \\ \hline v\ (\textrm{ft}/\textrm{s}) & 30 & 28 & 25 & 22 & 24 & 27 \\ \hline \end{array}$$ By interpreting these values as left-hand and right-hand endpoints for five intervals, find left-hand and right-hand estimates for the distance (in feet) that the motorcycle traveled during these sixty seconds.

Left-hand estimate = feet

Right-hand estimate = feet
