Answer 1

Step-by-step explanation:

solution: let the speed of car first = x

and speed of car second =x+4km/h

so, the distance of car fist after 4hours,

distance = speed × time

= 4 × x

=4x

the distance of second car ,

distance= speed×time

= (x+4)× 4

=4x +16

so, according to question,

4x + 16 +4x= 600 -16

8x+16=584

8x = 584-16

8x=568

x=568/8

x= 71km/h

Answer:

x= 71km/h
