APPARENT FAHRENHEIT TEMPERATURES DUE TO WIND-CHILL FACTOR (corresponding to actual temperatures and wind speeds)
25. Which of the following can be inferred from the table? I
The apparent temperature for an actual temperature of 20 degrees Fahrenheit and a wind speed of 15 miles
per hour is the same as that for an actual temperatrue of 60 degrees Fahrenheit and a wind speed of 40 miles per hour
II
At a constant wind speed as the actual temperature increases the difference between the actual and the apparent temperatures also increases
III
At a constant actual temperature of -10 degrees Fahrenheit the apparent temperature decreases at a constant rate as the wind speed increases
(A) I only (B) II only (C) I and III only (D) II and III only (E) I, II and III
这一题为什么是A啊,我怎么感觉A不对的啊,推算的话一个事-5,一个是43啊,怎么可能相等呢? |
