Answer:
Because the information was carried by ships
Explanation:
President Abraham Lincoln was assassinated in 1865. At that time, there was no mass media and no information processing technology. Neither was there rapid transport, like the airplanes. The nineteenth-century press was basically composed of some printed newspapers, so that for an information to cross the ocean, it was necessary that it be transported in ships. The journeys took a long time, the fastest transport took at least a week, as was the case with the arrival of the news of Lincoln's death in England.
