Samantha is the star of the cross-country team. During a recent morning run, Samantha averaged a speed of 5.8 m/s for 12.9 minutes. She then averaged a speed of 6.10 m/s for 7.1 minutes. Determine the total distance (in meters) that Samantha ran during her 20 minute jog.

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.
