The speed of car increases by 2 km after every 1 hiur.if the distance travelled in the first one hour was 35 km ,what was the total distance travelled in 12 hiur

• given the speed of the car is 35km it increases by 2 every hour
  in arithemtic progression the last term can be known by An=35+(12-1)2
  An =57
  the sum of the no's from 35 to 57 can be known by Sn=(35+57)12/2
  =552
