Respuesta :

During the 9 mile hike he  spends 2 periods of half hour swimming  = 1 hour.  
actual hiking time  = 3*3 = 9 hours

So total time = 9+1 = 10 hours

Answer:

4 hours

Step-by-step explanation:

John is hiking 9 miles. If it takes him an hour for every 3 miles, then you will do 9 ÷ 3.

9 ÷ 3 = 3

And it is stated that after every 4 miles, he takes a swim.

There will only be two swimming breaks since 4 can only go into 9 twice.

And two swim breaks will add up to an hour, adding an additional hour onto the 3 hours it takes for him to normally hike.

So, John hikes the 9 miles in 4 hours.
