Answer 2

Answer:

speed of car A is 25km/hr

speed of car B is 15km/hr

Step-by-step explanation:

Let

speed of car A be x km/hr

and speed of car B be y km/hr

According to the question,

in the same direction,

9x - 9y = 90

=> x - y = 10 ..........1

in opposite direction,

9/4x + 9/4y = 90

=> x+y / 4 =10

=> x+y =40............. 2

1+2 gives,

x-y=10

x+y=40

=>  2x = 50

x = 25

substituting x= 25 in 2

25 + y = 40

y = 15

=> speed of car A = 25km/hr

speed of car B = 15 km/hr
