After a cyclist has travelled 2/3 of her route, she gets a flat tire.Finishing the trip on foot, she spends twics as long walking as riding.How many times faster does she ride than walk?

I got 4 times faster is that right?

d=r*time

2/3 d=r*t
1/3 d=w+2t
divide the first equation by the second equation

2=r/(2w)
r/w-=4

yes, you are correct.
