108 मीटर लम्बी राजधानी एक्सप्रेस ट्रेन 128 किमी/घंटा की गति से चल रही है।
स्टेशन पर 148 मीटर लम्बी एक अन्य रेलगाड़ी खड़ी है
प्रयुक्त अवधारणा:
दूरी = गति × समय
गणना:
कुल दूरी 108 + 148 = 256 मीटर
⇒गति = 128 किमी/घंटा = 128 × 5/18 मीटर/सेकेंड = 320/9 मीटर/सेकेंड
अतः, समय = दूरी / गति
⇒ 256/ (320/9) = (256 × 9)/320 = 7.2 सेकंड
∴ सही विकल्प 4 है
