In the data table, distance is measured in meters and time is in seconds. Calculate the man’s average velocity using the equation: average velocity = total distance divided by time (I'm giving brainliest on this question and making a question for 70 points. If you help me out, ill give you the link for the 70 pointer, and give you brainliest)

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
