Question

Теплохід пройшов 120 км, рухаючись зі швидкістю 40км/год. Яку відстань подолає цей теплохід за той самий час, якщо збільшить швидкість на 20 км/год?

Answer 1

120/40=3часа в пути

40+20=60км/ч новая скорость

3*60=180км пройдет за 3 часа

Answer 2

Calculation of Distance Traveled by the Ship

To calculate the distance traveled by the ship, we can use the formula:

Distance = Speed × Time

Given that the ship traveled 120 km at a speed of 40 km/h, we can calculate the time it took to cover this distance:

Time = Distance / Speed

Substituting the given values:

Time = 120 km / 40 km/h = 3 hours

Therefore, it took the ship 3 hours to travel 120 km at a speed of 40 km/h.

Calculation of Distance Traveled with Increased Speed

Now, let's calculate the distance the ship will cover in the same amount of time if its speed is increased by 20 km/h.

The new speed of the ship will be 40 km/h + 20 km/h = 60 km/h.

Using the formula mentioned earlier:

Distance = Speed × Time

Substituting the values:

Distance = 60 km/h × 3 hours = 180 km

Therefore, if the ship increases its speed by 20 km/h, it will cover a distance of 180 km in the same 3-hour time period.

Conclusion

To summarize, the ship initially traveled 120 km at a speed of 40 km/h in 3 hours. If the ship increases its speed by 20 km/h, it will cover a distance of 180 km in the same 3-hour time period.
