Answer: The obvious answer is 5 miles.The not-so-obvious part is it depends on where he is when he starts. If he is on the equator, he is five miles from his point of origin. If his starting point was the south pole, and he drives five miles north, then west, then south, he will arrive back at his starting point. Before you disagree, consider that he is driving on a sphere not a flat plain.
Answer: Given is the calculated distance as well as the driving travel time, which does not take into account driving conditions, traffic, etc. The distance between Philadelphia, Pennsylvania and Key West, Florida is 1,361 miles. The resulting travel time is 22 hours and 45 minutes.
Answer: Did you mean West Hills? Near Los Angeles? If so, the distance is 2,051 km or 1,274 miles. Measured with the starting point at Granville St and W 10th Ave in Vancouver and ending at Burbank Blvd and Platt Ave in West Hills.
