Answer 1

Step-by-step explanation:

Answer:

Step-by-step explanation:

The distance between a and b is 210

Two cars travelled simultaneously

After 3 hours they travelled=210-54=156

speed=d/t

let the speed of two cars is x

x+x-8=156/3

2x-8=52

2x=60

x=30

30,30-8

∴30,22

Answer 2

Answer:

Speed of A is 30km/h and speed of B is 22km/h
