the Changs took a long car trip. The distance they traveled each day can be determined using d=rt, where r is - averege speed in males p/h and t is the number of hourse the traveled on first day the Changs traveled at a speed ho 3x/y for y+1/x. How far did they travel?

d = speed x time
d = (3x/y) . (y + 1/x)
d = (3x / y).(xy + 1) / x
d = (3/y).(xy + 1)
d = 3x + 3/y
d = 3.(x + 1/y) miles

If the 2d fraction is meant to be (y+one million)/x (all one fraction), then you definately get 3x/y * (y+one million)/x = 3(y+one million)/y The x cancels. or you ought to distribute the suitable to get (3y+3)/y From there you ought to even divide the two components of the numerator and make it 3 + 3/y on your answer.
