Detailed Solution
Download Solution PDFరైలు యొక్క పొడవు x మీ.అనుకుందాం.
⇒ రైలు యొక్క వేగం = (ప్లాట్ ఫామ్ యొక్క పొడవు + రైలు యొక్క పొడవు)/సమయం
ఇచ్చిన ప్రశ్న ప్రకారం
⇒ (110 + x)/ 13.5 = (205 + x)/18.25
⇒ (110 + x)/2.7 = 3.65
⇒ 401.5 + 3.65x = 553.5 + 2.7x
⇒ 0.95x = 152
⇒ x = 160
⇒ రైలు యొక్క వేగం = (110 + 160)/13.5 = 20 మీ/సె = 20 × (18/5) = 72 కి.మీ/గంట
