Question

find speed of two cars​

Answer 1

Answer:

Step-by-step explanation:

Let the speed of car at A be x kmph

and the speed of car at B be y kmph

As per the question,

5x - 5y = 100

x - y = 20 ... (1)

and x + y = 100 ... (2)

Solving (1) and (2), we get,

x = 60 and y = 40

Speed of the car at A = 60 kmph

Speed of the car at B = 40 kmph
