Bea can run 1/6 mile in 2 minutes. How long should it take her to run 2 miles?

math  Ms. Sue, Thursday, November 7, 2013 at 5:21pm
Cross multiply and solve for x.
(1/6)/2 = 2/x

math  anonymous, Thursday, November 7, 2013 at 5:23pm
is it 2/6

math  Ms. Sue, Thursday, November 7, 2013 at 5:27pm
How can that be? Don't you think it would take her much longer than 2 minutes to run 2 miles?
1/6x = 4
x = 4 / (1/6)
x = 4 * 6
x = _______ minutes

24 minutes.
But I don't get what x means in 1/6x = 4

math  Ms. Sue, Thursday, November 7, 2013 at 5:46pm
x is the unknown number of minutes it will take her to run 2 miles.
Yes, 24 minutes is correct.
