It takes lee ann 15.2 min to walk 1 mile. how long does it take her to walk 4.34 miles?

D = r * t
1 mile = r * 15.2 min
1/15.2 = r

4.34 = (1/15.2) *t

4.34* 15.2 = 1 t

t = 65.97 min

t = 66 min

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

The slope of the function is 0.5.
