Answer 1

Answer:

let speed of each car=x and y

a/q, 4.5(x+y) =600-123=477

x+y=106km/h

x-y=6km/h

so, x=56 km/h

y=50km/h

Answer 2

Step-by-step explanation:

Let  = the speed of the slower car in km/hr

 = the speed of the faster car in km/hr

Let  = the distance in km that 

the slower car travels in  hrs

 = distance in km 

the faster car travels in  hrs

--------------------------------- 

Equation for slower car:

(1) 

Equation for faster car:
