The Very Large Array (VLA) is a set of 30 dish radio antennas located near Socorro, New Mexico. The dishes are spaced 1.0 km apart and form a Y-shaped pattern, as in the diagram. Radio pulses from a distant pulsar (a quickly rotating neutron star) are detected by the dishes; the arrival time of each pulse is recorded using atomic clocks. If the pulsar is located 44.0° above the horizontal direction parallel to the right branch of the Y, how much time elapses among the arrival of the pulses at adjacent dishes in that branch of the VLA?
