Required:

(b) Jocatt operates in the energy industry and undertakes complex natural gas trading arrangements, which involve exchanges in resources with other companies in the industry. Jocatt is entering into a long-term contract for the supply of gas and is raising a loan on the strength of this contract. The proceeds of the loan are to be received over the year to 30 November 2011 and are to be repaid over four years to 30 November 2015. Jocatt wishes to report the proceeds as operating cash flow because it is related to a long-term purchase contract. The directors of Jocatt receive extra income if the operating cash flow exceeds a predetermined target for the year and feel that the indirect method is more useful and informative to users of financial statements than the direct method.(i) Comment on the directors’ view that the indirect method of preparing statements of cash flow is more useful and informative to users than the direct method. (7 marks)(ii) Discuss the reasons why the directors may wish to report the loan proceeds as an operating cash flow rather than a financing cash flow and whether there are any ethical implications of adopting this treatment. (6 marks)Professional marks will be awarded in part (b) for the clarity and quality of discussion. (2 marks)

节能是汽车性能的一个重要指标，但同一辆汽车每百公里的耗油量与行驶速度的快慢是否有关呢？端午节期间，小明乘坐爸爸的汽车由达州去成都，于是他决定借此机会对这一问题进行探究．他们去时走高速公路，回来时走318国道，得到了下表所示的数据．

（2）若汽车在高速公路上行驶180km，求：

①汽车行驶的时间为多少？

②若该汽车发动机的功率为60kW，效率为30%，则汽车发动机所做的有用功为多少？
