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 ?

Options

A. 6 hours
B. 5 hours
C. 7 hours
D. 8 hours

Answer

A

Explanation

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 .
