An aircraft cruises at \( M = 0.85 \) where the speed of sound is \( 295 \) m/s. Its true airspeed is nearest to
Answer: A
True airspeed is the Mach number times the local speed of sound, so \( 0.85 \times 295 = 250.8 \) m/s, about 488 knots. Dividing rather than multiplying gives 347 m/s and would imply the aircraft was supersonic, which the stated Mach number contradicts.
