What would the average speed in kph of a horse and rider be if they cover a total distance of 14 km in 249 minutes

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

Average speed = (14 km) / (249 min)

Average speed = (14/249) (km/min)

Average speed = (14/249) (km/min) x (60 min/hr)

Average speed = (14 x 60 / 249) km/hr

Average speed = 3.37 km/hr
