A delivery drone can fly at a speed of 50 kilometers per hour. It needs to make a delivery to a location 75 kilometers away. After dropping off the package, the drone returns to the base at a speed of 40 kilometers per hour due to headwinds. If the drone spends 10 minutes at the delivery location, how much time, in total, does the drone spend on this trip? Let's think step by step and output the final answer within \boxed{}.
