Question
The average speed of a car traveling from city X to city
Y is 60 km/h. On its return trip from city Y to city X, due to traffic, the car’s average speed drops by 25%. If the total time taken for the entire round trip is 14 hours, what is the distance between city X and city Y?Solution
Speed of car from city Y to X = 75% of 60 = 45 km/h -Constable/1726828921-126.JPG)
= 360/7 km/h Total distance covered in 14 hours = 14×360/7 = 720 km Distance from city X to city Y = 720/2 = 360 km
