EXAMPLE 6 After covering a distance of 30 km with a uniform speed there is some defect in a trainengine and therefore, its speed is reduced to 4/5 of its original speed. Consequently, the train reachesits destination late by 45 minutes. Had it happened after covering 18 kilometres more, the train wouldhave reached 9 minutes earlier. Find the speed of the train and the distance of journey
