Absolute pressure at the bottom of the lake = pressure due to water height + Air pressure = Density of water*gravitational acceleration* height + 101.3 kPa
Therefore,
Absolute pressure = 1/1000(1*10^3*9.81*29.1) + 101.3 = 285.471+101.3 = 386.771 kPa
15+3=18km/hour
Think about it like this. The boat is going 15 faster than the river, and the river is going 3 faster than the bank, so the boat is going 18 faster than the river bank

Power is the ratio between energy and time:
In our problem we have E=76 J and t=3.7 s. Therefore, the power is
