at noon on the 6th January is (omitting seconds) in 19° 29′
, and on the 10th January at noon he is in 20° 30′
, which gives a daily motion of 59 minutes. We must find his place for 3 p.m. on the 9th January. As 24 hours are to 3 hours, so are 59 minutes to the time required; this equals about 7 minutes, which we add to the
