The estimated total pressure a diver experiences below the surface of the water is equal to the sum of the estimated water pressure and the estimated atmospheric pressure. At a depth of $h$ meters below the surface, the estimated total pressure $P_1$, in kilopascals (kPa), a diver experiences is given by $P_1=10h+101$. After maintaining a depth of $h$ meters, the diver descended $d$ additional meters. The estimated total pressure $P_2$, in kPa, the diver experienced after descending these $d$ additional meters is given by $P_2=10d+341$. What is the estimated total pressure, in kPa, the diver experienced at a depth of $h$ meters below the surface?
