After covering a distance of 30 km with a uniform speed there is some defect in a train engine and therefore, its speed is reduced to 4/5 of its original speed. Consequently, the train reached its destination late by 45 minutes, had it happened after covering 18 kilometres more, the train would have reached 9 minutes earlier. Find the speed of the train and the distance of journey
A. Original speed = 10 Km/hr, Length of the journey = 90 Km
B. Original speed = 15 Km/hr, Length of the journey = 100 Km
C. Original speed = 25 Km/hr, Length of the journey = 110 Km
D. Original speed = 30 Km/hr, Length of the journey = 120 Km
