### Question

**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 truck? **

A. 6 hours

B. 5 hours

C. 7 hours

D. 8 hours

**Answer:** A

**Solution:**

**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.**
