yesterday-between-9-00-a-m-and-6-00-p-m-at-airport-x-all-flights-to-272436.htmlYesterday between 9:00 a.m. and 6:00 p.m. at Airport X, all flights to Atlanta departed at equally spaced times and all flights to New York City departed at equally spaced times. A flight to Atlanta and a flight to New York City both departed from Airport X at 1:00 p.m. yesterday. Between 1:00 p.m. and 3:00 p.m. yesterday, did another pair of flights to these 2 cities depart from Airport X at the same time?
(1) Yesterday at Airport X, a flight to Atlanta and a flight to New York City both departed at 10:00 a.m.
(2) Yesterday at Airport X, flights to New York City departed every 15 minutes between 9:00 a.m. and 6:00 p.m.
In here both flights are equally spaced and their spacing aligns atleast every 3 hours according to S1 bc flight at 10 and 1, so according to this atleast a flight will depart at the same time at 4pm but we arent sure if before 4 it will too, is that correct ?
