Step-by-step explanation:
Let the speed of passenger train be x km/hour. Then speed of express train will be x + 11 km/hour
Time taken by the passenger train = 132 over straight x space hours.
Time taken by the express train = fraction numerator 132 over denominator straight x plus 11 end fraction space hours.
According to question
132 over straight x minus fraction numerator 132 over denominator straight x plus 11 end fraction equals 1
Thus speed of passenger train is 33 km/hour and that of express train = 44 km/hour
