The number of homework problems you can complete is given by the function \(h(t)=\frac{2}{5} t+6\), where t represents time in minutes. The number of homework assignments you can finish in a given period of time is given by the function \(A(h)=\frac{h}{15} +1\), where A represents the number of homework assignments you can finish. Find \(\left(A\circ h\right)(60)\) and tell what that value means.
