<PRE><B>Question 85474</B>
A runner practiced at a park near his home. His pedometer indicated that he ran 300 feet in 10 seconds. About how many minutes would it take him to complete the mile?
:
Find the number of seconds (t) required to complete 5280 ft (1 mile)
:
t = 10(5280/300)
t = 5280/30
t = 176 seconds, which is 2 min, 56 seconds
:
You could also use the ratio method:
{{{(10/t)}}} = {{{300/5280)}}}
cross multiply and solve for t:
