Question
The distance between two places Bangalore and Hyderabad is 660 km. Anand starts from Bangalore with a certain uniform speed while Sonu starts from Hyderabad at the same time with a uniform speed that is 4km more than that of Anand. If they meet each other after 5 hours, find the speed of each.
Solution
Let the speed of Anand be x km/hr.
Then Speed of Sonu = (x + 4)km/hr.
In 5 hours, Anand travels = 5x km
In 5 hours, Sonu travels = 5(x + 4)km
Distance between two places = 660km
The total distance travelled by Anand and Sonu will be same as the distance between two places
ATQ, 5x + 5(x + 4) = 660
⇒ 10x + 20 = 660
⇒ 10x = 640
⇒ x = 64 km/hr
Speed of Anand = 64km/hr
Speed of Sonu = 64 + 4 = 68km/hr.
