Given: A car after travelling 60 km distance met with an accident that slowed down its speed to 4/5th of its former speed and thus arrived at its destination 45 minutes late. Had the accident occurred 32 km further, the car would have reached the destination 30 minutes late Calculation: Let the initial speed of car = x km/hr; Decreased speed = 4x/5 km/hr. If the accident occurred 32 km further that means speed of car in that 32 km would have been x km/hr instead of 4x/5 km/hr and that would have made difference of 15 minutes(45 – 30) in time taken; 32/(4x/5) – 32/x = 15/60 ⇒ 8/x = 1/4 ⇒ x = 32 km/hr ∴ Initial speed of the car = 32 km/hr
