Solve the Problem $t$ ) Since the Beginning of the Race, as Shown in Race

Solve the problem.
-A runner is competing in an 8-mile race. As the runner passes each miles marker (M) , a steward records the time elapsed in minutes ( $t$ ) since the beginning of the race, as shown in the table. What is the runner's average speed over the first 2 miles? Round your answer to four decimal places.
$\begin{array}{l|lllllllll}\mathrm{M} & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 \\\hline \mathrm{t} & 0 & 15 & 29 & 43 & 55 & 67 & 80 & 93 & 109\end{array}$

A) $0.0690 \mathrm { miles } / \mathrm { min }$
B) $0.0649 \mathrm { miles } / \mathrm { min }$
C) $14.4928 \mathrm { miles } / \mathrm { min }$
D) $0.0862 \mathrm { miles } / \mathrm { min }$
