1 mile to work you walk 4 miles per hour how long does it take to get to work

Question

How long does it take to get to work if you live 1 mile away and you walk 4 miles an hour?

Answer 1

Dylan,

 

If the distance to work is 1 mile and you can walk at 4 miles per hour, then you can walk 1 mile in ¼ hr = 15 minutes.

 

To set up the "equation" think about it this way:  (1 mile/ t) = (4 mile/ 1 hr)

 

so 1/t = 4/1 hr  

 

now multiply both sides by t to get 1 = t·(4/1 hr), next divide both sides by (4/1 hr)

 

t = 1/(4/ 1 hr) = 1 hr/4 = ¼ hr = 15 min.

 

Answer 2

distance=rate*time

d=rt

1=4t

1/4=4t/4

1/4=t

t=1/4 hour or 15 minutes
