One car starts from A and another from B at the same time. If the cars travel in the same direction at different speeds, they meet in 5 hours. If they travel towards each other, they meet in 1 hour. What are the speeds of the two cars? Let Speed of first car be x km/hr & Speed of second car be y km/hr If travelling in same direction Distance travelled by 1st car = AC = AB + BC Distance travelled by 2nd car = BC Difference of distance travelled = (AB + BC) – BC = AB = 100 km Distance travelled by 1st car – Distance travelled by 2nd car = 100 km (Speed of first car × 5 hours) – (Speed of 2nd car × 5 hours) = 100 km 5x – 5y = 100 5(x – y) = 100 (x – y) = 100/5 x – y = 20 If travelling in opposite direction Distance travelled by 1st car = AD Distance travelled by 2nd car = BD Sum of distance travelled = AD + BD = AB = ...

[Solved] The distance between two places A and B is 140 km. Two cars

Question Download Solution PDF The distance between two places A and B is 140 km. Two cars x and y start simultaneously from A and B, respectively. If they move in the same direction, they meet after 7 hours. If they move towards each other, they meet after one hour. What is the speed (in km/h) of car y if its speed is more than that of car x? Given: Distance between A and B = 140 Concept used: Speed = Distance/Time If both cars going in the same direction, then relative speed = (S 1 - S 2) km/hr If both cars going opposite direction, then relative speed = (S 1 +S 2 ) km/hr Calculation: Let the speed of x carand ycar be b km/hr and akm/hr According to the question, (a+ b) = 140/1 ⇒ (a + b) = 140 ----(1) ⇒ (a– b) = 140/7 ⇒ (a– b) = 20 ----(2) By adding equation (1) and equation (2) we get ⇒ a= 80 So, speed of y car = 80 km/hr ∴ The speed (in km/h) of car yis 80

Places A and B are hour. What are the speeds of the two cars? Speed Time and Distance The speed is the ratio of the distance covered by a body and the time taken by the body to cover it. When two bodies are traveling towards each other, they cover the entire gap together at the point of meeting, hence the speed is added. The opposite is applied to the condition when two bodies are moving apart. Answer and Explanation: 1

Points A and B on a national highway are at a distance of 1 2 0 k m from each other. One car starts from A and another from B at the same time. The car which starts from A moves with a constant speed along the direction A B and the second moves with a constant speed in the same direction from B. The first car overtakes the second car in 4 hours. However, if the second car moves from B towards A then the two meet each other after 2 hours. Find the speed of the car which starts from A.

[Solved] Two cars start towards each other, from two places A and B w

Given: The distance between A and B = 160 km Speed of car 1= 50 km per hour Speed of car 2= 30 km per hour Concept used: If two trains are moving in opposite directions at u m/s and v m/s, then relative speed is = (u + v) m/s Formula used: Time = Distance/Speed Calculation: Relative speed = (speed of car 1+ speed of car 2) ⇒ Relative speed = (50 + 30) = 80 km/hr ⇒ Time = Distance/Time ⇒ Time = 160/80 = 2 hours They start at the same time 08∶ 10 AM ⇒ Time =08∶ 10 AM + 2 = 10 : 10 AM ∴ They will meet each other at 10 : 10 AM

[SOLVED] Places A and B are 100 km apart on a highway One car st

SOLUTION Let the speed of car which starts from A be x and from B be y Therefore,speed of car from A in 5 hours = 5 x speed of car from B in 5 hours = 5 y Case 1 Both the cars travel in the same direction, Therefore, 5 x - 5 y = 100 5 (x - y) = 100 Thus , x -y = 100/5= 20 Also, x = 20 + y . . . . . . . . (1) Case 2 Both the cars travel towards each other, Therefore, x + y = 100 From (1) , + y = 100 20 + 2 y = 100 2 y = 100 - 20 2 y = 80 Thus, y = 80/2 = 40 Km/hr Substituting y = 40 in (1), x = 20 + y = 20 + 40 = 60 Km/hr Thus, the speed of car which starts from A is 60 Km/hr and that of the car which starts from B is 40 Km/hr
