Douglas Adams' The Hitchhiker's Guide To The Galaxy, Book 1 Of 3 by John Carnell

An ordinary Englishman is swept off Earth moments before its demolition to make way for an interstellar bypass and thrust into a wildly comic voyage across space with his eccentric alien friend, a two-headed ex‑President, a resourceful woman, and a deeply depressed robot. They rely on a whimsical electronic travel guide while encountering absurd bureaucracies, improbable adventures, and a quest for the ultimate answer to life, the universe, and everything—only to discover that the questions may be more interesting than the answers.
