A robotic system delivers 120 food packages in a grid-based community. If each delivery takes 4.5 minutes and the robot moves directly between adjacent points with no detours, and the farthest point is 10 km away, what is the total travel time assuming optimal routing and constant speed?

**How Smart Delivery Robots Are Reshaping Urban Logistics in the U.S. — And Why the Numbers Matter** Field tests of autonomous food delivery robots are multiplying across American cities, driven by demand for faster, greener last-mile solutions. One emerging model delivers up to 120 meal packages across grid-based neighborhoods—designed to serve dense urban block patterns with minimal backtracking. Each delivery takes 4.5 minutes, and the farthest customer lies 10 kilometers from the central hub. The real question: how long does the robot take to complete its route, logically and reliably? This isn’t just a technical curiosity—it reflects broader shifts in urban efficiency, sustainability, and digital trust in smart infrastructure. --- ### Why This System Is Gaining Attention Now
