200 मीटर लांबीची एक मालगाडी ताशी 48 किमी वेगाने प्लॅटफॉर्मवर उभ्या असलेल्या माणसाला पार करते. त्याचवेळी उलट्या दिशेने ताशी 60 किमी वेगाने जाणारी 150 मीटर लांबीची गाडीही त्या माणसाला पार करते. त्या दोन गाड्यांना त्या माणसाला पार करायला लागणाऱ्या वेळेत कितीचा फरक पडतो ? A 200 m long goods train crosses a man standing on the platform at a speed of 48 km/hr. At the same time another goods train 150 metres long crosses that man at a speed of 60 km/hr in the reverse direction. Calculate the difference between time taken by both the trains to cross the man ?
Time taken by a train to cross a stationary man = Length of train / Speed of train. Calculate for both trains and find the absolute difference in time.
आगगाडी A ची लांबी x मीटर्स आणि वेग u कि.मी./तास आहे. आगगाडी B ची लांबी y मीटर्स आहे, आणि वेग v कि.मी./तास आहे. जेंव्हा त्या दोन गाड्या उलट दिशेने समांतर धावतात तेंव्हा त्या परस्परांना t मिनीटात ओलांडतात. पण जेंव्हा त्या एकाच दिशेने समांतर धावतात तेंव्हा त्या 4t मिनीटात परस्परांना ओलांडतात. जर u = 50 कि.मी./तास, तर v ची किंमत किती ? Train A has a length of x meters and speed of u km/hour. Train B has a length y meters and speed of v km/hour. The two trains take t minutes to cross each other when they travel parallel in opposite directions, and 4t minutes to cross each other when they travel in the same direction. If u = 50km/hour. What is the value of v ?
Set up equations for relative speed in opposite direction (u+v) and same direction (u-v) using distance / time relationships, and solve for v given u = 50.
