Question

What is the average speed in kilometers per hour of a horse that gallops a distance of 15 km in a time of 30 min?

Answer 1

Distance = 15 km
time = 30 min
        = 30/60 hrs
        = 1/2 hr

speed = distance / time
           = 15 / 1/2 (0.5)
           = 30 km / hr

Therefore, speed of horse = 30 km / hr.
