问题
According to the graph above, at approximately what speed, in miles per hour (mph), is the energy per distance used in running approximately twice the energy per distance used in walking?
选项
A、Between 6.5 and 7 mph
B、Between 5.5 and 6 mph
C、Between 4.5 and 5 mph
D、Between 3.5 and 4 mph
E、Between 2.5 and 3 mph
答案
E
解析
标题:能量与速度根据上图,大约在多大速度(以mph为单位)时,跑每单位距离消耗的能量约是走单位距离所消耗能量的2倍?
解:本题的正确答案为(E)。题目中图形的横轴代表速度(mph),纵轴代表单位距离所消耗的能量(焦耳/米);图中的实线是跑步时速度与能量之间的关系,虚线代表走路时速度与能量之间的关系。根据以上分析再结合图形可知,在速度为2.5--3 mph时,跑每单位距离的路程所消耗的能量约是走单位距离的路程所消耗能量的2倍。
