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
