Brishti went on a 8-hour trip in a car, before the trip the car had traveled a total of x kms till then, where x is a whole number and is palindromic, At the end of his trip the car had had traveled a total of 26862 km. If Bristi never drove at more than 110 km/h, then the greatest possible average speed at which see dove is?

• A. 90
• B. 80
• C. 110
• D. 100

Answer 1

Answer: (D)

100

Answer 2

Considering that the trip took place across a total of 26862 kilometers and lasted for 8 hours.
The kilometers traveled up to immediately before the trip is 26862 - 8s, which should likewise be a palindrome, if the average speed of the vehicle during the journey is's'.
Among the choices the reading will be $26862 - 110\times8 = 25982$ (Not a palindrome)
If s = 110 the reading will be $26862 - 100\times8 = 26062$
If s = 100 it's a palindrome.
=> s = 100 is the right choice.
The correct answer is 100.
