To calculate the propeller tip speed (in miles per hour) under these conditions, we can use the formula: Tip Speed (mph) = RPM Propeller Diameter 1 60 1 5280 60 Tip Speed (mph)=RPMPropeller Diameter 60 1 5280 1 60 Given: RPM = 2700 Propeller Diameter = 72 inches Substituting the values into the formula: Tip Speed (mph) = 2700 72 1 60 1 5280 60 Tip Speed (mph)=270072 60 1 5280 1 60 Tip Speed (mph) = 2700 72 1 60 1 5280 60 Tip Speed (mph)=270072 60 1 5280 1 60 Tip Speed (mph) 589.06 mph Tip Speed (mph)589.06 mph Therefore, the propeller tip speed under these conditions is approximately 589.06 mph. So, the closest option is 589 mph
