Atrain traveled 3/12 of the distance between two cities in 1/2 of an hour. at this rate, what fraction of the distance between the two cities can the train travel in one hour. write a fraction.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
