Download Solution PDFएक ट्रेन P स्थानका पासून सुरू होते, Q, R, S, T स्थानकांमधून धावते आणि U स्थानकाला पोहोचते. ती Q, R, S आणि T स्थानकावर अनुक्रमे 2 मिनिटे, 4 मिनिटे, 6 मिनिटे आणि 8 मिनिटांसाठी थांबते. P आणि U मधील अंतर 50 किमी आहे. जर ट्रेन स्थानका दरम्यान 70 मिनिटे एकसमान वेगाने धावत असेल, तर P आणि U स्थानकांदरम्यान ट्रेनचा सरासरी वेग (किमी/तास मध्ये) किती असेल?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
अंतर = 50 किमी,
एकूण धावण्याची वेळ = 70 मिनिटे,
स्थानकांवर थांबण्याची वेळ = 2 + 4 + 6 + 8 = 20 मिनिटे
संकल्पना:
सरासरी वेग = एकूण अंतर/एकूण वेळ
गणना:
⇒ थांब्यांसह एकूण वेळ = 70 + 20 = 90 मिनिटे = 90/60 = 1.5 तास
⇒ सरासरी वेग = 50 किमी/1.5 तास = 100/3 किमी/तास
म्हणून, P आणि U स्थानकांदरम्यान ट्रेनचा सरासरी वेग 100/3 किमी/तास आहे.
