By 10:00 a.m., Andrew travels alone for 2 hours at 39 km/hr, covering a distance of 78 km and leaving a remaining distance of 637 km minus 78 km, which is 559 km. After 10:00 a.m., they travel towards each other, so their relative speed is the sum of their individual speeds, which is 39 km/hr plus 47 km/hr to equal 86 km/hr. Using the formula Time = Distance / Speed, the time taken to meet after 10:00 a.m. is 559 km divided by 86 km/hr, which equals 6.5 hours or 6 hours and 30 minutes. Adding this duration to 10:00 a.m. results in a meeting time of 4:30 p.m.
