Step-by-step explanation:

Answer 2

Answer:

Speed of Car A  and B are 35 km / hr and 25 km / hr respectively.

Step-by-step explanation:

Let the speed of car at A is x km / hr and at B is y km / hr

Case 1.

8 x - 8 y = 80

x - y = 10

x = 10 + y ... ( i )

Case 2.

4 / 3 x + 4 / 3 y = 80

x + y = 60

x = 60 - y ... ( ii )

From ( i )  and  ( ii )

10 + y = 60 - y

y = 25

Putting value of y in ( i )

x = 10 + 25

x = 35 .
