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

Cross multiply and solve for x.
(1/6)/2 = 2/x 
is it 2/6

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 
x is the unknown number of minutes it will take her to run 2 miles.
Yes, 24 minutes is correct. 
thanks

You're welcome.
