Ratio of The Average Speed = 40 : 35 = 8 : 7.
So, Ratio of the Time Taken = 7 : 8.
Difference In Time = 15 min
8 - 7 = 15
1 = 15
Thus,
8 = 8 * 15 = 120 Minutes.
Second Train Takes 120 minutes (2 hours) to reach there.
Distance = 35 * 2 = 70 Km.
So, Ratio of the Time Taken = 7 : 8.
Difference In Time = 15 min
8 - 7 = 15
1 = 15
Thus,
8 = 8 * 15 = 120 Minutes.
Second Train Takes 120 minutes (2 hours) to reach there.
Distance = 35 * 2 = 70 Km.
