You and your friends decide to travel, on foot, to your favorite beach at the Jersey Shore. Your speed for the first part of the trip is 2.2 mi/hr. Twenty-three minutes after starting your trip, the group decides to stop at a convenience store for a drink. After stopping at the convenience store for five minutes, you continue your travels for 0.9 hour and then stop at a local fast-food restaurant for a bite to eat. You spend 20 minutes eating your favorite burger and 480 seconds after continuing your journey, you stop to use the restroom for 0.5 hr. Now that everyone feels a little lighter, the group increases its speed to 5.5 km/hr and spends the next 900,000 milliseconds traveling to a friend’s beach house to get sun block. After spending five minutes getting the sun block and raiding your friend’s pantry for snacks, the group starts “fist-pumping” in anticipation of their arrival at the beach. Eleven minutes and twenty five seconds later, you and your friends finally feel the warm sand beneath your feet. Approximately how many miles away is the beach?
