Answer:
The time save by Simpson is 25.8 minutes.
Explanation:
Given that,
Velocity of the car, v = 48 km/h
Distance covered by the car, d = 144 km
Let t is the time taken by the car. Speed of an object is given by distance covered per unit time. It is given by :
t = 3 hours
If the velocity is increased to 56 km/h to the east. Time taken is given by :
t' = 2.57 seconds
The time save by Simpson increasing his average velocity is given by :
or
So, the time save by Simpson is 25.8 minutes. Hence, this is the required solution.
