இரயிலின் நீளம் x மீ ஆக இருக்கட்டும்.

⇒ இரயிலின் வேகம் = (நடைமேடையின் நீளம் + இரயிலின் நீளம்)/நேரம்

கேள்வியின் படி,

⇒ (110 + x)/ 13.5 = (205 + x)/18.25

⇒ (110 + x)/2.7 = (205 + x)/3.65

⇒ 401.5 + 3.65x = 553.5 + 2.7x

⇒ 0.95x = 152

⇒ x = 160

⇒ இரயிலின் வேகம் = (110 + 160)/13.5 = 20 மீ/வி = 20 × (18/5) = 72 கிமீ/மணி
