on average , exante express trains are 50km/h faster than Paral passenger trains. A paral train requires 60% more time than an exante train to travel 1800 km from matsay to rawindi

calculate the average speed of each train

calculate the time it takes each train for the journey

e = p + 50

time = distance / rate
... 1.6 (1800 / e) = 1800 / p

substituting
... 1.6 [1800 / (p + 50)] = 1800 / p

solve for p, then substitute back to find e and the times
