you walk from your house to a local coffee shop to get an espresso. You average  a speed of 2.4 m/s on your way there. After your espresso, you decide to run directly  back to your starting point with an average speed of 5.6 m/s. Assume you spend 4  minutes at the coffee shop. If your average speed for this entire trip is 1.9 m/s, what is  the distance between your house and the coffee shop?
