WebMar 24, 2024 · Pete traveled 1,380 miles in two days. The first day, he traveled 1.5 times as far as he did the second day. He drove 828 miles on the first day. Solution: x+1.5x=1,380; 2.5x=1,380; x=1380/2.5=552; Therefore Peter travelled 552 miles on the second day and 1.5 x 552 or 828 miles on the first day. WebIf we instead try a value that doesn't work, say x=3 (try 2x+3=7 @ 3), Algebra Calculator shows a red "not equals" sign instead.
