A person crosses a 600 m long street in 5 minutes. What is the speed in km/h?

Convert distance to km and time to hours, then use Speed = Distance / Time.

Step-by-step calculation
Distance = 600 m = 0.6 kmTime = 5 minutes = 5/60 h = 1/12 hSpeed = 0.6 / (1/12) = 0.6 × 12 = 7.2 km/h

Final Answer
7.2 km/h
