The Velocity of a Car Was Read from Its Speedometer

question 129

Short Answer

The velocity of a car was read from its speedometer at ten-second intervals and recorded in the
table. Use the Midpoint Rule to estimate the distance traveled by the car. $$\begin{array} { | c | c | c | c | c | } \hline t ( \mathrm {~s} ) & v ( \mathrm { mi } / \mathrm { h } ) & & t ( \mathrm {~s} ) & v ( \mathrm { mi } / \mathrm { h } ) \\\hline 0 & 0 & & 60 & 54 \\\hline 10 & 34 & & 70 & 67 \\\hline 20 & 43 & & 80 & 77 \\\hline 30 & 36 & & 90 & 37 \\\hline 40 & 45 & & 100 & 42 \\\hline 50 & 45 & & & \\\hline\end{array}$$
