A train is targated to run from Delhito Pune at an average speed of 80 kph but due to repairs of tracklooses 3 hrs in the first part of the journey. If then accelerates at arate of 20 kph2 till the speed reaches 100 kph. Its speed isnow maintained till the end of the journey. If the train now reachesstation in time, find the distance (in km) from when it has startedacceleration.previously answered by akash goyal but anwer is not 2200 km it is 849 km
