Question

If a man travels 65 Km in 5days by walking 7 hours a day, in how many days will he travel 156 Km by walking 14 hours a day.

Answer 1

Step-by-step explanation:

First of all, let's find the speed at which the man is walking. As you know

Speed = Distance / time

Now distance given is 65km and total time taken to cover these 65km is ( 3 * 7.5 ) = 22.5 hours.

So, speed of man is 65 / 22.5 kmph that is 26/9 kmph.

So we have calculated the speed of man.

Now he has to cover a distance of 156 km. And now he walks for 8 hours a day.

So distance travelled by man in one day walking at speed of 26/9 kmph for 8 hours is ( 26/9 * 8 ) km = 208/9 km.

Therefore number of days he travels is

156/ ( 208/9 ) = 27/4 days that is 6 days and 18 hours.
