एक गाडी 60 किमी/तास वेगाने प्रथम 33 मिनिटांचा प्रवास करते,
पुन्हा 70 किमी/तासाच्या वेगाने 33 मिनिटे
वापरलेली संकल्पना:
अंतर = वेग × वेळ
सरासरी वेग = (एकूण अंतर)/(एकूण वेळ)
गणना:
\({\rm{Average\;speed}} = {\rm{\;}}\frac{{\frac{{33}}{{60}}\: ×\:60\: + \:\frac{{33}}{{60}}\: ×\: 70}}{{\frac{{66}}{{60}}}}\)
⇒ सरासरी वेग = (33 × 60 + 33 × 70)/66
⇒ सरासरी वेग = (60 + 70)/2 = 65 किमी/तास
∴ गाडीचा सरासरी वेग हा 65 किमी/तास आहे.
संकल्पना:
जेव्हा समान अंतरासाठी वेळ समान असेल,
सरासरी वेग = (v1 + v2)/2
जेथे v = वेग
गणना:
सरासरी वेग = (70 + 60)/2 = 65 किमी/तास
∴ गाडीचा सरासरी वेग हा 65 किमी/तास आहे.
