The table below shows the distance s in feet a ball rolls down an inclined plane in t seconds.
\begin{tabular}{|c|c|c|c|c|c|c|}
\hline
t & 0 & 1 & 2 & 3 & 4 & 5\\
\hline
s & 0 & 10 & 40 & 90 & 160 & 250\\
\hline
\end{tabular}
The distance s for t \equal{} 2.5 is:
<spanclass=′latex−bold′>(A)</span>45<spanclass=′latex−bold′>(B)</span>62.5<spanclass=′latex−bold′>(C)</span>70<spanclass=′latex−bold′>(D)</span>75<spanclass=′latex−bold′>(E)</span>82.5
