Question

Автомобиль за 4 часа прошел 240км. Сколько км он пройдет за 7 часов, если его скорость увеличится на 6км/ч?

Answer 1

240/4=60 (км/ч) скорость автомобиля

60+6=66(км/ч) скорость после увеличения

66*7=462 (км)

Ответ: 462 км пройдет автомобиль 

Answer 2

240:4=60км/ч скорость автомобиля
(60+6)*7=462 км пройдет автомобиль за 7 часов 

Answer 3

Calculating the Distance Traveled

To calculate the distance the car will travel in 7 hours with an increased speed, we can use the formula:

Distance = Speed × Time

Given that the car initially traveled 240 km in 4 hours, we can calculate its initial speed using the formula:

Initial Speed = Distance / Time

Let's calculate the initial speed of the car using the given information.

Initial Speed = 240 km / 4 hours = 60 km/h

Now, we can calculate the increased speed of the car:

Increased Speed = Initial Speed + 6 km/h

Increased Speed = 60 km/h + 6 km/h = 66 km/h

Using the increased speed, we can calculate the distance the car will travel in 7 hours:

Distance = Increased Speed × Time

Distance = 66 km/h × 7 hours = 462 km

So, the car will travel 462 km in 7 hours with the increased speed of 6 km/h.

Conclusion

The car will travel 462 km in 7 hours with its speed increased by 6 km/h.
