Ravi runs at a speed of 45 m/min. After 6 minutes, Siva starts chasing Ravi at a speed of 60 m/min. A dog starts running along with Siva at a speed of 80 m/min. If the dog reaches Ravi and comes back to Siva, and goes back to Ravi, and so on and so forth, until Siva meets Ravi, then find the total distance covered by the dog in metres.

Answer:
1,440 Metres is covered by the Dog.
Step-by-step explanation:
Distance covered by Ravi in 6 Minutes = 45 x 6 = 270 Mts
Siva started 6 Minutes later than Ravi.
Siva and Ravi met after X Minutes
60X = 45X + 270
60X - 45X = 270
15X = 270
X = 270 / 15 = 18
Ravi and Siva met after 18 Minutes
Speed of Dog = 80 Metres
The Distance covered by Dog = 80 x 18 = 1,440 Metres
∴ The Distance covered by Dog is 1,440 Metres
