An airplane flies eastward and accelerates uniformly. At one position along its path it has a velocity of 26.5 m/s. It then flies a further distance of 47700 m and its velocity is 48.3 m/s. Find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 47700 m.
