A Man travelled a distance of 60 km in 8 hours. He travelled partly on foot at 4 km/hr and partly on
bicycle at 9 km/hr. What is the distance travelled on foot?
Choose one
A) 16 km
B) 14 km
C) 12 km
D) 10 km
E) None of these
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 = 60 km   So,   4x + 8(9-x) = 60   =&gt; 4x = 12   =&gt; x = 3   So distance traveled on foot = 4(3) = 12 km   Answer: Option 12 km
