A driver is riding his MC in a fixed speed from point A to B.
in some point, he noticed that the numbers of km he already
passed, equals to the number of minutes he got left to drive
until he reaches the B point. When he finally reached point B,
he then find out that the number of kilometers is equal to the
sum of the minutes he drove in the first part of his trail.
Q:what was his speed from point A to point B?

Is the last part, that the whole distance from A to B (in km) equals the sum of the digits(?) of the time he took for the first part (in minutes)?

I mean the time for the first part in minutes,
if every minute he will pass is 1 km, after half an hour
he'll be half way from his goal. the sum is 30 in this case: midA/B30km + 30minutes = fixed speed 60km/h
Apology if i wasn't clear.
