You look directly overhead and see a plane exactly 1 km above the ground flying faster than the speed of sound. By the time you hear the sound from the plane, the plane has trav- eled a horizontal distance of 1.4 km. Find the speed of the plane in units of meters per second. (The speed of sound is v, = 340 m/s.)
