If a human being traveling 2.5miles per hour walking--how many days would it take to travel 4427 miles?

-------------------------------------------------------

Engr. Ronald say: t = d/v
t = (4427miles)/2.5mph
t = 1770.8 hours.. or 73.78 days or 74 days answer//

Jim Moor say: Walking 24 hours a day:
4427 mi (1 hour/2.5mi) (1 day/24hr) = 73.783333333333333 days

Now round answer to 2 digits since 2.5 has 2 digits:
Rounded: 74 days

Walking only 8 hours per day:
4427 mi (1 hour/2.5mi) (1 day/8 hr walking) = 221.35 days
Rounded: 220 days
-
MICHAEL K say: 4427 miles/2.5 miles = 1,770.8 hours then 1,770.8 hours/24 hours = 73.783 days.
-
JSG say: In one day, that person would travel 2.5 miles/hr * 24 hours = 60 miles.
It would take 4427/60 days = 73 47/60 days = 73 days 18 hours 48 minutes to travel 4427 miles.
-
ideaquest say: 2.5 miles / hour

(1) If he walks 24 hours per day (non-stop)

4427/2.5 = 1770.8 hours

1770.8/24 = [ 73.783 days ]

(2) If he walks 12 hours a day

73.783 x 2 = [147.567 days]
-
Krishnamurthy say: 4427/60 = 73.783333333.... days
-
BENARD say: 4427/2.5=1770.8hrs

so 1770.8/24= 73.78
since a day is a whole number then
-
Manny say: Assuming the person doesn't stop and maintains exactly the same speed consistently; 73 days, 18 hours, and 48 minutes.
-
billrussell42 say: 4427 mi / 2.5 mi/hr = 1771 hr
1771 hr x 1 day/24hr = 73.8 days
with no time for rest or sleep.

walking 8 hours a day, that becomes 221 days
-
TexHabs say: Do you know how many hours are in day? If so it shouldn't be too difficult to determine.
-
Annie say: Also, how many pairs of shoes would this person go through?
-
Tim say: i don't know why you have to see this kind of math problem. why can't the teacher come up with something more realistic.
-
james say: On foot with good roads or trails. Figure 20 miles per day. Open country 15 miles per day. Rough terrain figure 7 miles per day. So along the coast road. 222 days. Over the mountain along the road 443 days. Remember 12 hours a day is most you can walk. You need some days to do repair. So add days for that to figures above.
-
Rain say: 1770.8 hours
-
Kenneth say: 4427 miles / 2.5 miles per hour = 1770.8 hours, or about 73.8 days
-
nbsale say: How many hours in a day?
How many miles does he cover in that time.
Divide that into 4427.
-
Lôn say: First find how many hours it would take...
4427/2.5 = 1770.8 hours
To change to days, divide by 24
1770.8/24 = 73.78 days.
-
Dan say: About a year of Sundays.
-
Atheist Dude say: Need a calculator for that.
-
say: take a bike
-
say: Numerous
-
Fido say: Assuming they walk 12 hrs/day then 4427/(2.5*12)=148 days
-
Math Explorer say: Use formula distance = rate * time
In this case your distance is 4427 miles and your rate is 2.5 miles per hour.

if distance = rate*time then time = distance / rate.
-
Markus Imhof say: That answer would have at least a factor of four of uncertainty, depending on how many hours per day they could spend walking, and how many days per week.

On top of that would be, if this is a real life problem, how much time they might have to spend with buereaucratic obstacles, from being held up for vagrancy to having to wait for visa.

So, best case, with 14 hours (14 hours walking, 2 hours for eating and hygiene, 8 hours of sleep) per day on 7 days per week (which basically mandates a couple more people for the supply train), you'll get 4427/(14*2.5) = 126.5 days. Cut that down to a more realistic 7 hours of walking on 5 days a week, and you'll get a bit more than 354 days. Call it a year.
