Answer:
not possible
(infinite Speed)
Step-by-step explanation:
a person wanted to travel from charbagh to alambagh with an average speed of 60km/h by car. The distance between charbagh and alambagh is 2 km. Due to heavy traffic, he could travel at 30 km/h for the first kilometer of his journey
his average speed target of 60km/h
Distance = 1 km
Average speed = 30k/hr
Time taken = 1/30 hr = 2 mins
Total Distance = 2 km
Total Average speed = 60k/hr
Time taken = 2/60 hr = 2 mins
He has to travel next 1 km in 2 - 2 = 0 min
So its not possible to achieve average speed of 60 km/hr
(mathematically he has to travel with infinite speed for next km to achieve average speed of 60 km/hr)
