Question 299434: A woman can ride a bicycle 25 miles in the same time that it takes her to walk 5 miles. if she can ride 8 mph faster than she walk, how fast can she walk? Answer by Greenfinch(383) (Show Source):
You can put this solution on YOUR website! Let her walk at X mph, She therefore cycles at X + 8 mph
so 25/(X + 8) = 5/X
25X = 5X + 40
20X = 40
X = 2, so she walks at 2 mph and cycles at 10 mph
Check - 25 miles at 10 mph takes 2.5 hours
walking 5 miles at 2 mph also takes 2.5 hours
