Explanation / Answer
In the summer solstice the daylenth in the northern hemisphere is greater than the 12 hr of equator because of the 23.5 degree tilting and the daylength decreases at southern hemisphere
change value of time = 4min= 1 degree rotation
H= hour angle
20 degree north = 80 min= 1hr 20 min
daytime = 12+1 hr 20 min = 13 hr 20min
20degree south
20 degree south = 4x20 = 80 min= 1hr 20 min
daytime = 12 - 1 hr 20 min = 10 hr 40min
20degree north
20 degree south = 4x40 = 160 min= 2hr 40 min
daytime = 12 + 2 hr 40 min = 14 hr 40min
