Borax was mined in Death Valley, California, during the nineteenth century. It was transported from the valley by a massive wagon, each pulled by a team of 25 mules. Suppose each mule’s power output was 732 W (about 1 hp). If in a certain time interval the total work done by the team on the wagon was 2.45 × J, how long was that interval of time? Show your work below and bold your final answer.
