Question

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 . What should his speed be for the remaining journey to his average speed target of 60km/h?

Answer 1

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)
