Average speed = (total distance covered) / (time to cover the whole distance)
 
Total distance = (516 + 368) = 884 yards
Total time  = (6 + 4) = 10 minutes  

Average speed = (884 yards) / (10 minutes)

Average speed = 88.4 yards/minute  (C)


Other ways to write the same speed:

-- 4.42 feet/second
-- 265.2 feet/minute
-- 53.04 inches/second
-- 5,304 yards/hour
-- 3.014 mph (rounded)
-- 810.07 furlong/fortnight
