Speedometer readings for a vehicle (in motion) at 7-second intervals are given in the table. t (sec) v (ft/s) 0 39 7 38 14 38 21 49 28 37 35 39 Estimate the distance traveled by the vehicle during this 35-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
