Question

Теплоход за 8ч прошел 312 км. за сколько часов он пройдет 231км если его скорость уменьшиться на 6км/ч?

Answer 1

312:8=39 км в час была скорость
39-6=33 км в час новая скорость
231:33=7 часов
Ответ 7 часов

Answer 2

1)312:8=39(км/ч)-изначальная скорость теплохода
2)39-6=33(км/ч)-измененная скорость теплохода
3)231:33=7(ч)

Answer 3

Calculation of Time Required to Travel 231 km at a Reduced Speed

To calculate the time required for the ship to travel 231 km at a reduced speed, we can use the formula:

Time = Distance / Speed

Given that the ship initially traveled 312 km in 8 hours, we can determine its initial speed using the formula:

Initial Speed = Distance / Time

Substituting the given values:

Initial Speed = 312 km / 8 hours = 39 km/h

Now, we need to calculate the reduced speed by subtracting 6 km/h from the initial speed:

Reduced Speed = Initial Speed - 6 km/h = 39 km/h - 6 km/h = 33 km/h

Finally, we can calculate the time required to travel 231 km at the reduced speed:

Time = Distance / Speed = 231 km / 33 km/h

Using this formula, we can determine the time required for the ship to travel 231 km at a reduced speed.
