By 9 a.m. + T hours, it has traveled for (T − 1) hours at 100 mph, so its distance from New York is 100(T − 1) miles. Hence, counting from Chicago’s end, it has covered 790 − 100(T − 1) miles (but we typically just use the sum-of-distances approach, below).\n\n3) When they meet, the sum of the distances they have traveled equals the total distance of 790 miles:\n   80T + 100(T − 1) = 790.\n\n4) Solve for T:\n   80T + 100T − 100 = 790  \n   180T − 100 = 790  \n   180T = 890  \n   T = 890 / 180 = 4.9444... hours (approximately).\n\n   In hours and minutes, this is about 4 hours and (0.9444 × 60) ≈ 56.7 minutes, so about 1:56 p.m.\n\n5) Find how far they are from Chicago when they meet. Since the first train’s distance from Chicago is 80T:\n   Distance = 80 × 4.9444... ≈ 395.6 miles.\n\nAnswer:\n• They meet at about 1:56 p.m.  \n• They are approximately 396 miles from Chicago at the meeting point."}},"exampleRequest":{"model":"o1","messages":[{"role":"user","content":"A train leaves Chicago at 9am traveling at 80mph toward New York, 790 miles away.
