Question 929435
x = biking speed
y = running speed
---
s = d/t
t = d/s
---
bike:
t = 18/x
---
run:
t = 6/y
---
18/x = 6/y
18y = 6x
x = y + 10
---
put the system of linear equations into standard form
---
6x - 18y = 0
x - y = 10
---
copy and paste the above standard form linear equations in to this solver:
