8 laps time 1/4 mile is 2 miles
Average speed in miles per hour:
2 mi / 12.5 min * 60 min/hour = 9.6 mph
Average velocity is zero, since velocity is directional and the person jogged around a track. [I mention that in case this was set up as a trick question.]
But if we're really looking for average SPEED in m/s we can easily convert:
A mile is about 1.6 km, so it's about 1600 m
(2 mi * 1600 m/mi) / (12.5 min * 60 s/min) = 1800 / 750 = 2.4 m/s
