How long  does it take to walk 1 km? (for a lazy teenager)?

there are 2.23 km in a mile and it takes about a half hour to walk a mile so about 15 minutes i would assume.\n\nYou can run a mile in 4-6 minutes.

When you mention "a day", I can assume you plan to run very often, and when you ask this kind of question here, but not face to face with an experienced person, I assume you are a newbie. Correct me if I am wrong, I just try to help.\n\nRun every km in around 7 min for 30 min a day will do good for a healthy newbie. If there is a special condition, talk to the doctor first.\n\nLuckily, none of my students say I am foolish so far.

The most I ever walked in one 24 hour period was 66 miles.\n\nSafe, is completely different.  Although you say you walk 5 miles, how long have you been doing it?  how often do you walk 5 miles? Is it flat or heavy terrain?  do you wear gear, or light? etc.\n\nI would say if you do already at least 5 miles a day and it is already comfortable (i.e. you don't stop, constant pace, and your heart rate does not increase much by the end), you can pop it up 100%  to 200% for a day within a week.  So, 15  miles should be tolerable.\n\nI would monitor your heart rate.  watch your baseline,and as you see it increase try to keep it at 50 - 70% above it... See how far you get within the same time as it takes you to do the 5 miles walk currently.  This should give you some guideline how much you could handle...\n\nYou should be able to keep a 3 to 3.2 mph speed.

It takes me four minutes and fifty-four seconds to run a mile. I am fourteen years old and will be turning fifteen in May.

Swimming is the best. Next is walking in normal speed 5-6 km per hour early morning for 45 minutes to  one hour,daily or at least 5 days in a week..

The average person can walk about 3 miles/hour on flat, easy ground.  Therefore if you can keep that pace up for 12 hours, you could potentially walk 36 miles.

It depends on how fast you run/walk.  If you are doing a combo of running and walking, you can probably finish in 45 minutes or less.

OK, this is a simple unit conversion problem, buddy. First, get your measurements into similar units: in this case, change your minutes into hours (1 hr/60 min). You'll end up with.\n\n(40 km/h * .5 h) + (60 km/h * .25 h)\n\nThe hours will cancel out, and you'll be left with the kilometers.\n\n20 km + 15 km = 35 km\n\nIn this instance, the direction of travel doesn't matter: the question asks the distance traveled, not how far away from the point of origin you are.

I'm going to use minutes instead of hours.\nWe know that on the first trip, D = 120S (D=distance, S=Speed of first trip).\nWe know that one the second trip, D = 90(S+6).\n\nTherefore 120S = 90S + 540, or 30S = 540, and S = 18kph.\nTherefore the distance is 36 kilometers.\nChecking, 24(1.5) for the second trip also = 36.

400 meters is a 1/4 mile or 5280feet divided by 1/4 which is 1320 feet. At a fast pace that should take about 2.5 to 3 minutes to walk. Fast runners run it in under a minute

I'd certainly jump on the treadmill and begin building up.  This will mean turning the incline to 1% to 2% and then walking on it at a comfortable pace. \n\nYou didn't mention what your fitness level is, but 16 Min miles should be pretty easy if you are in reasonable shape.   The challenge for you will be doing 13.1 miles.  Definitely work on your endurance and build up to walks of 1 - 2 miles -- gradually.  Every week from here on out, try adding one more mile, one day each week.  Try to walk 2 - 4 miles every other day.\n\nBe sure that you have sensible shoes. If you are going to be running, be sure you have running shoes (no those cross trainers don't count).\n\nAlso don't worry about being a walker.  If it is a big race, you won't be alone as a walker.\n\nGood luck.
