Currently, you would ask "How long does it take to get from Rotherham to London?" You would do 156/60, which would be 2.6 hours. 2.6 hours is 156 minutes (2 hours, 36 minutes).
9:36 is when Kim would reach London, so yes.
I’m pretty sure there are infinite solutions as the system of equations are equivalent to each other.
X > 5 or x < -3
Hope this helped! :)
