if the distance between two station is 6000 km and there are 10 stops between them train takes i^2 mints if i is odd and train takes i mints if i is even and the speed of train is 90km/hr
then how much tme it will take ?

• Ans: 69h 55m
  
  Explain:
  .."""There is few mistakes in RAKESH'S Solution, so i did correct it """.
  
  Time taken by train at stoppages
  at stops 1,3,5,7,9 time taken is 1^2,3^2,5^2,7^2,9^2 mins respectively
  at stops 2,4,6,8,10 time taken is 2,4,6,8,10 mins respectively
  
  total time at stops = (1^2+3^2+5^2+7^2+9^2)+(2+4+6+8+10)= 165+30 = 195m = 3h 15m
  
  Time taken by train(without any stop) = 6000/90 = 200/3 h = 66h 40m
  
  Total time = 66h 40m + 3h 15 m = 69h 55m

• 66 hr 56 min
  time to cross odd numberd stations = 165 min
  time to cross even numbered stations =30 min
  total distance covered between source to 10th stop is (3 hr 15 min)*90km/hr=292.5 km
  remaing distance between 10th stop to destination is 6000-292.5=5707.5km
  time to take remaing distance covered is 5707.5/90=63.41 hr
  
  so total time taken between source and destination is 63.41+3.25 hr
  = 66 hr 39 min.

• @Sneha : Man is walking at 5km/hr, that means in 15 mins, he walks 1.25km

• short trick::
  large distance*3-small distance
  so;
  50*3-20=130
