In March of 1999, Bertrand Piccard and Brian Jones attempted to become the first people to fly around the world in a hot air balloon. Based on the average speed of 97.8 kilometers per hour, the distance that they traveled in kilometers, d, can be modeled by d(t) = 97.8t, where t is the time in hours. The traveled a total of 478 hours. %3D Select the option that represents the domain of the function d(t). O [0,478] O (0,478)
