Question

The distance between two stations A and B is 230 Km . Two cars start simultaneously from A to B in the opposite direction and the distance between them after 3 hours is 20 km. If the speed of one car is less than that of the other by 10 km/hr , find the speed of each car ​

Answer 1

Answer:

40km/hr and 30km/hr

Step-by-step explanation:

Let the speed one car be X km/hr

and speed of another car be (X-10) km/hr

So,

3X + 3(X-10) = 230-20

or, 3X+3X-30 = 210

or, 6X = 210+30

or, X = 240/6

or, X = 40

Hence, the speed of one car is 40 km/hr

and the speed of another car (40-10)=30 km/hr
