The car covers 240 km in 5 hours at its usual speed.
The car then travels at half of its usual speed.
Formula used:
Speed = Total Distance/Total Time
Calculation:
Usual Speed = Total Distance/Total Time = 240/5 = 48 km/h
Half Speed = Usual Speed/2 = 48/2 = 24 km/h
The time taken to cover the same distance (240 km) at half speed would be:
240 km/24 km/h = 10 h
Extra Time = 10 - 5 = 5h
So, the car will take an extra 5 hours to cover the same distance at half of its usual speed
