Can someone please help me with question no. 3.2.2

so the train departed Durban at 18:30 in 24hours format, or namely 6:30pm, and arrived at Kimberly at 14:50 on the next day, namely 2:50pm Thursday.

let's see, from 6:30 to 7pm is 30 minutes

from 7pm to 12am or 00:00 is 5 hours

and from 12am to 2:50 or namely 00:00 to 14:50 is well, 14 hours and 50 minutes

if we add the hours first, that'd be 5 + 14 = 19, and then we add the minutes that'd be 30 + 50 = 80 minutes, so that'd be a total of 19 hours and 80 minutes, wait a second!!!, 80 minutes is really 60 + 20, or 1 hour and 20 minutes, so that'd make it 19 hours plus 1 hour and 20 minutes, 20 hours and 20 minutes.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
