When the Wife tries to explain where she spent her money.
A train starting @ 0Km/hr, on a 90km track with 3 towns on route, each town is 5km long and the train is 5kms long but starts @ 0 of 90KM. Is allowed to travel 40km/hr outside town and 5km/hr while on town tracks. And accelerates @ 5km/hr/minute. How much time is required to come to a complete stop at the end of the track. First town is 10km in then each is 10km apart.
Whats the answer??
