To find out how much time it will take for Mukesh to travel 28 km, we can set up a proportion based on the information given.
Mukesh walks 10 km in 5 hours. Therefore, his speed can be calculated as:
Speed = Distance / Time = 10 km / 5 hours = 2 km/h
Now, we can use this speed to determine the time it will take to travel 28 km:
Time = Distance / Speed = 28 km / 2 km/h = 14 hours
Therefore, it will take Mukesh approximately 14 hours to travel 28 km.
