Answer:
It will take 3 hrs and 30 min. Here is why:
Step-by-step explanation:
If 4 miles is in one hour the closest to 14 is 12 without going over. 4 miles per hour times 3 is 12 miles per 3 hours but the issue is how do we find how long the other 2 miles take? Well if we go back to 4 miles per hour we just need to divide both sides by 2. We get 2 miles per half an hour or 30 minutes so adding 12 miles+ 2 miles we get 14 miles. Then adding our time 3 hour and 30 minutes that is our answer!
Answer : It takes 3 hours and 30 minutes for Martha to walk 14 miles.
