Answer:
speed of each car is 8 km/hr. and 64 km/hr.
Step-by-step explanation:
distance between A and B is 270 km
speed of the first car is 8 km/hr.
let speed of the another 2nd one is x km/hr.
after 3 hours , first car covered 3×8 = 24 km
after three hours the second car covered 3x km
after 3 hours distance between the first car and the second car is
= 270 - (24+3x) km
= 246 - 3x
according to question , 246 - 3x = 54
⇒ 3x = 192
⇒ x = 64
then the speed of 2nd car is 64 km/hr.

Answer:
speed of first car=8km/hr
first car covered =3×8 =24 km
=270-(24+3x)km
=246-3x
246-3x=54
3x=192
x=64
therefore the speed of second car is 64km/hr
