A car travels a distance of 2000m. If the first half distance is covered at 40 km/hour and the second half at velocity v and if the average velocity is 48 km/hour then the value of v is
Text Solution
Verified by ExpertsThe correct answer is:
B
< V > = 
V 1 = 48 = 
⇒ 48 = 
⇒ V + 40 = 
V
⇒ 24 V + 960 = 40 V ⇒ 16 V = 960
V = 60 km/hr
