Question: 3 miles equals how much time?
Answer: Average people usualy walk 3.1miles/hour. But if you're an athlete, you should be at your destination in about 40 minutes because you walk 4miles/hour, 4 – 3 miles = 1mile, 1mile is one 3rd of 3miles (3/1=3) so 60minutes(one hour)/3minutes = 20 minutes, then 60 minutes - 20 minutes = 40 minutes.
