The car covered 270 km in 3 hours. How many more kilometers will it cover in 6 hours if its speed decreases by 8 km / h?

Let’s solve the task of actions with explanations.
1) 270: 3 = 90 kilometers per hour – the speed of the car, since in three hours it covered a distance of 270 kilometers;
2) 90 – 8 = 82 kilometers per hour – this will be the speed of the car if it is reduced by 8 kilometers per hour;
3) 82 * 6 = 492 kilometers – the distance that the car traveled at a speed of 82 kilometers per hour in 6 hours of movement.
Answer: 492 kilometers.
