Due to increased property taxes and an aggressive road development plan, the city of New Berlin has been able to increase the road capacity of two of its roads. The capacity along the road represented by the path from node 1-node 2 has been increased from 2 to 5. In addition, the capacity from node 1-node 4 has been increased from 1 to 3. What impact do these changes have on the number of cars per hour that can travel from east to west?
