How do you solve:

Question

A woman can bicycle 112 miles in the same time as it takes her to walk 32 miles. She can ride 10 mph faster than she can walk. How fast can she walk? Using  as your variable to represent the rate at which she walks, write an equation using the information as it is given above that can be used to solve this problem.

Answer 1

32/w = 112/b

32b=112w

32(10+w)=112w

32w+320 =112w

80w=320

w=4 mph walking speed

b=14 mph bike speed
