In a reinforced concrete beam-column, the increase in the flexural strength along with the increase in the axial strength occurs

A linear relationship is observed between speed and density on a certain section of a highway. The free flow speed is observed to bekm per hour and the jam density is estimated asvehicles per km length. Based on the above relationship, the maximum flow expected on this section and the speed at the maximum flow will respectively be
