Answer 2

Step-by-step explanation:

Answer:

270 km

Step-by-step explanation:

Let x be the distance between the City A and City B

Car 1 Case:

Distance =x

Speed of Car 1 = 60 km/hr

Time =\frac{Distance}{Speed}Time=

Speed

Distance

Time =\frac{x}{60}Time=

60

x

Car 2 Case:

Distance =x

Speed of Car 2 = 108 km/hr

Time =\frac{Distance}{Speed}Time=

Speed

Distance

Time =\frac{x}{108}Time=

108

x

Now we are given that one car takes 2 hours lesser time than the other car for the journey

So, \frac{x}{60}-\frac{x}{108}=2

60

x

−

108

x

=2

\frac{x}{135}=2

135

x

=2

x=135 \times 2x=135×2

x=270x=270

Hence the distance between City A and City B is 270 km.
