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

running time = 66h 40m - 3h 15 m = 63h 25m

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.
