Apizza bot travels at an average rate of 4 mph it is sent on a delivery toy house 1.5 miles away how long will it take the bot to make the delivery every time back to the restaurant

Round trip for robot, because it has to get to the destination and back = 3 miles Rate of robot is 4 miles per hour. t = time for robot to make delivery. 4r = 3 r = 3/4 = 0.75 It will take the robot 0.75 hours to make the delivery and come back to re restaurant.
