Question: Can you guide me through solving this problem: Sid traveled 110 miles in 2 hours. If Sid then traveled an additional 140 miles in 3 hours, what's the average speed he was traveling?
Answer: 
After traveling 110 miles at first, Sid traveled 110 + 140 = 250 miles in total
Since he spends 3 hours traveling after the first 2 hours, he traveled 3 + 2 = 5 hours
On average, Sid traveled 250 miles / 5 hours = 50 miles per hour.
