1 answer:
Answer:
25 mph
Explanation:
The average speed is the ratio of the total distance traveled to the total time taken to cover that distance. It is given by the formula:
Average speed = total distance / total time taken
The distance traveled on the horseback = velocity * time = 30 mph * 2 h = 60 miles
The second distance traveled = velocity * time = 15 mph * 1 h = 15 miles
The total distance traveled = 60 miles + 15 miles = 75 miles
The total time taken = 2 hr + 1 hr = 3 hr
Hence, the average speed = 75 miles / 3 hr = 25 mph
