Question 931712: Rachael's bike got a flat tire and she must walk the rest of the way to work. The bike was being ridden at 10 mph, and Rachel walks at speed of 6 mph. the distance from home to work is 22 mi, and the total time for the trip was 3 hr. How far did she have to walk?

x = distance walked
y = distance ridden
z = time walked
w = time ridden
---
s = d/t
d = st
t = d/s
---
x + y = 22
---
time walked:
z = x/6
---
time ridden:
w = y/10
---
total time:
z + w = 3
x/6 + y/10 = 3
---
x + y = 22
x/6 + y/10 = 3
---
put the system of linear equations into standard form
---
x + y = 22
0.16666666666x + 0.1y = 3
---
copy and paste the above standard form linear equations in to this solver:
