Problema Solution
Ross started his trip at 9 AM with the car's odometer reading 36863 which is a palindrome (reads the same left to right as right to left). He averaged 60 MPH for the trip and when he arrived at his destination the car's odometer read the next possible palindrome with all odd digits. At what time that day did Ross arrive at his destination?
Answer provided by our tutors
the next possible palindrome with all odd digits is 37973
let
t = the time of the trip in hours
v = 60 mph the average sped
d = (37973 - 36863) mi the distance that Ross drove
since speed= distance/time that v = d/t we follows t = d/v
t = (37973 - 36863)/60
t = 18.5 hr
t = 18 hr 30 min
18 hr 30 min after 9 AM is 3:30 AM next day.
