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 ... (Thinking)

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
