The SR-71 Blackbird reconnaissance aircraft is primarily made of titanium and typically flies at speeds above Mach 3. In flight, the length of the SR-71 increases by about 0.20 m from its takeoff length of 32.70 m. The average coefficient of linear expansion for titanium over the temperature range experienced by the SR-71 is 10.1 × 10−6 K−1. What is the approximate temperature of the SR-71 while it is in flight if it started at 20 °C?
