A truck covers a distance of 376 km at a certain speed in 8 hours. How much time would a car take at an average speed which is 18 kmph more than that of the speed of the truck to cover a distance which is 14 km more than that travelled by the truck?
Speed of the truck = Distance/time
= 376/8 = 47 kmph
Now, speed of car = (speed of truck + 18) kmph
= (47 + 18) = 65 kmph
Distance travelled by car = 376 + 14 = 390 km
Time taken by car = Distance/Speed
= 390/65
= 6 hours
