On the way to the bike shop she travels at 6 miles per hour so it takes her 1/6 of an hour to go a mile and hence it takes her d/6 hours to go the d miles to the bike shop. Using the same logic how long does it take her to walk the d miles home? The sum of these two times is 1 hour. Solve for d. Make sure you check your answer. Penny
