Train X covers distance between 2 stations 45 minutes faster than train Y. What is the distance between the 2 stations if the average speed of train X is 54 km/hr and that of train Y is 21 km/hr?

Let the distance be D kilometers; using the formula Time = Distance / Speed, the difference in travel times is (D / 21) - (D / 54) = 45/60 hours. Solving this equation yields D multiplied by (54 - 21) / (21 multiplied by 54) = 0.75, so D equals 0.75 multiplied by 1134 / 33, which is approximately 25.77 km. The result is 25.77 km.
