Why you didn't use the same formula eqn eq 22-1 as for the first entry?? From where you got the second equation based on headway? Thank you

From page 22-3 "When the conflicting flow rate approaches zero, the maximum entry flow is given by 3,600 s/h divided by the follow-up headway, which is analogous to the saturation flow rate for a movement receiving a green indication at a signalized intersection"

Can we just use the exhibit 22-22 to solve this problem? Thank you
