Correction:Find the speed?
Final Speed: 72km/h
Let the speed be v km/h .
Then, time take will be v/2 h.
Distance = speed * time
=> 2592 = v * v/2
=> v^2 = 2592*2
=> v = 72km/h
Therefore, uniform speed of car is 72km/h covered 2592km in 36 h.

Answer:
Step-by-step explanation:
Let the time taken be x.
Then the speed is 2x.
Speed = Distance/Time
Or, 2x =2592/x
Or, 2x^2 = 2592
Or, x^2 = 2592/2 = 1296
x = sqrt(1296) = 36
Time taken = 36 hours
Speed = 2*36 = 72 km/h
