Ireally need this was due friday! i will mark brainiest!
hint: use the equation for average speed.

Average speed = (total distance covered) / (time to cover the distance)

You only need the first and last points from the table.

First point: Position=0, Time=0

Last point: Position= 16.34, Time = 2.34 hours

Total distance covered = 16.34 (miles ?  km ?)

Time to cover the distance = 2.34 hours

Average speed = (16.34 miles) / (2.34 hours)

Average speed = 6.983 mile/hour
