Speedometer readings for a vehicle $($in motion$)$ at $14-$second intervals are given in the table.

$\backslash$table$[[t($sec$),v($ft$/$s$)],[0,24],[14,34],[28,24],[42,35],[56,25],[70,34]]$

Estimate the distance traveled by the vehicle during this $70-$second period using the velocities at the beginning of the time intervals.

distance traveled ~~ feet

Give another estimate using the velocities at the end of the time periods.

distance traveled ~~ feet
