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

ANSWER: The basic equation which relates speed, time and distance is given as, speed = distance / time (1) As the horse travels 15 km in 30 minutes, it’s speed will be, average speed = 15 / 30 = 1/2 = 0.5 km/minutes. But this is not the proper unit which we use generally. So, let’s convert it into km/h. As we know that, 1 hour = 60 minutes, 1 min = (1 / 60) hrs 0.5 km/minutes = 0.5 / (1/60) = 0.5 × 60 = 30 km/h CONCLUSION: The average speed of the horse is 30 km/h.
