A train does a journey without stopping for 8 hours. If it had traveled 5 km an hour faster, it would have done the journey in 6 hours 40 min. What is its slower speed?	Choose one:
A) 35 kmph
B) 25 kmph
C) 40 kmph
D) 50 kmph
E) None of these
Let its slower speed = V km per hour   Here, the distance is same in both the cases   Using the formula = V1 x t1 = V2 x t2   or, V x 8 = (V + 5) x 20/3   or, 24V = (V + 5) x 20   V= 25 km/h   Thus, The slower speed of train is 25 km/h.   ANSWER:25 kmph
