Solution
Nora sees: 1001
The next palindrome distance is: 1010
because (1001) is already a palindrome, and the next one is (1010).
Find the distance
\(1010-1001={9\text{miles}}\)
Use speed = 40 mph
\(\text{Time}=\frac{\text{Distance}}{\text{Speed}} =\frac{9}{40} =0.225\text{ hours}\)
But 0.225 isn't among the choices.
So let's check the interpretation: the milestone distance decreases as she travels toward her destination. Starting at 1001 miles, the next palindrome distance to destination is 999 miles.
Distance traveled:
\(1001-999=2\text{ miles}\)
Time:
\(\frac{2}{40}={0.05\text{ hours}}\)
Therefore:
Answer: A
