A circular jogging track forms the edge of a circular lake that has a diameter of 2 miles. Johanna walked once around the track at the average speed of 6 miles per hour. If t represents the number of hours it took Johanna to walk completely around the lake, which of the following is a correct statement?
Choose the correct choice from the following choices:
A) 0.5< t < 1.5
B) 1.75< t < 2.0
C) 2.0 < t < 2.5
D) 2.5 < t < 3.0
E) 3 < t < 3.5
D=2, and R=1   circumference thus is 2pi miles   we know that she walked 6mph   knowing the formula rt=D, we can deduce that t= D/r   D is 2pi miles and r is 6mph   t = 2pi/6   pi can be rewritten as 22/7   2*22/7 = 44/7 and multiply this by 1/6 = 44/42. This is greater than 0.5, but less than 1.5, therefore, 0.5&lt;t&lt;1.5. 0.5&lt; t &lt; 1.5nswer choice 0.5&lt; t &lt; 1.5.
