A Man travelled a distance of 48 km in 7 hours.
A Man travelled a distance of 48 km in 7 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?
Answer/Solution
20 km
Steps/Work
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 = 48 km
So,
4x + 7(9-x) = 48
=> 3x = 15
=> x = 5
So distance traveled on foot = 4(5) = 20 km
Answer: Option B
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 = 48 km
So,
4x + 7(9-x) = 48
=> 3x = 15
=> x = 5
So distance traveled on foot = 4(5) = 20 km
Answer: Option B
