    Palindromic

    The odometer of the car shows 15,951 miles. The driver noticed that this number is palindromic. Surprised, the driver saw his third palindromic odometer reading 5 hours later. How many miles per hour was the car traveling in those 5 hours

    I have the number to be 16061 is this correct?

    So they would be going 22 miles per hour


    Thank you

    Not sure if I understand the question correctly ...

    Since the next palindromic numbers would be: 16\begin{array}{c}0\\\bold{\color{red}1}\\2\\3\\4\  \..\end{array}61 the third palindrome is 16161.

    Thir palindrome

    Palindrome, is a number that remains the same when its digits are reversed.
    15951
    16061
    16161 Third palindrome
    Problem is telling us driver saw third palindrome after 5 hours.

    distance = 16161-15951=210 miles

    r=d/t = 210/5 = 42 mph
