Answer 1

Answer:

x+y=100---------1

x-y=20----------2

ON ADD EQUATION 1 AND 2

we get x=60

put x=60 in eqaution1

y=40

Answer 2

Answer:

$\huge{\mathcal{\underline{\green{Answer}}}}$

Let the speed of car at A be x km/h

and the speed of car at B be y km/h

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 km/h

Speed of the car at B = 40 km/h
