A person walks at a speed of 5 km/h for 2 hours and then runs at a speed of 10 km/h for 1 hour. What is the total distance covered?

A. 15 km

B. 20 km

C. 25 km

E. None of the above

Answer: C. 25 km

Distance covered while walking = 5 km/h * 2 h = 10 km. Distance covered while running = 10 km/h * 1 h = 10 km. Total distance = 10 km + 10 km = 20 km.
