Answer:
Speed of car: 45 km/hr
The time that is taken to complete journey: 6 hours
Distance traveled: Speed x Time
=45 x 6
=270 kilometers
Speed needed to complete journey in 5 hours: (Speed x Time)/5
= (45x6)/5
= 270/5
=54 km/hr
Therefore, the car needs to travel 54 km/hr to finish the journey in 5 hours.

Speed doubles therefore time taken will be halved
