Time taken (in hrs) by two trains X and Y to travel the distance from Lucknow to Chandigarh via the same route on four different days is given in the following bar graph. Study the graph carefully and answer the question given below:
If the distance between Lucknow and Chandigarh is 754 km, then what is the difference between the average speed (in km/hr) of the trains X and Y on Day 3?
Given:
Distance between Lucknow and Chandigarh = 754 km
Time taken by train X on Day 3 = 13 hours
Time taken by train Y on Day 3 = 20 hours
Solution:
Train X on Day 3:
Average Speed of Train X = ≈ 58km/hr
Train Y on Day 3:
Average Speed of Train Y = = 37.7km/hr
Difference in Average Speeds:
