First we need to list what we know from the text. Bob's speed : 13,48 mph and 6hour a day. The distance is 392,5 miles. How do we get the number of hours? Distance/Speed = 392,5/13,48 = 29,1172~ 29,12hours. Then how do we get the number of days? The race will take 29,12 hours for Bob and he can do 6 hours of it every day ==> 29,12/6 = 4,85333333 ~ 4,85 days. Give an answer with your solution and proper wording form the text. Eg.: Bob will need 4,85 days to complete this race.
