Elvis starts driving from his house and travels west for 5 hours. Then he turns around and travels east for 8 hours. If he was driving at an average speed of 18mph for both parts of the journey, how far is he from his house now?
During the first part of the journey he travels west for 5 hours at a speed of 18mph so he covered a distance of 5*18 = <<5*18=90>>90 miles
Then he travels east at the same speed for 8 hours so he covered a distance of 8*18 = <<8*18=144>>144 miles
His distance from his house now is the difference between his east and west movements which is 144-90 = <<144-90=54>>54 miles
