A Man travelled a distance of 61 km in 9 hours. He travelled partly on foot at 4 km/hr and partly on a bicycle at 9 km/hr. What is the distance travelled on foot? A. 14 km B. 10 km C. 12 km D. 16 km Answer Workspace Report Discuss Answer with explanation Answer: Option D Explanation Let the time in which he travelled on foot = x hour Time for travelling on bicycle = (9 – x) hr Distance = Speed * Time, and Total distance = 61 km So, 4x + 9(9-x) = 61 => 5x = 20 => x = 4 So distance travelled on foot = 4(4) = 16 km Workspace
