Mo Fara can run 10k in 27:44! What was his average speed?

speed = distance/time
if 27:44 is 27 minutes and 44 seconds, convert 27:44 to seconds
27:44 = 1664 seconds
and if 10k is in meters then
speed = 10000 m / 1664 seconds = 6m/s

if 27:44 is 27 hours and 44 minutes, convert 27:44 to seconds
27:44 = 99840 seconds
speed = 10000 m / 99840 s = 0.1 m/s
