Question

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

Answer 1

120/40=3 часа потратил теплоход на дорогу

40+20=60 км/ч -скорость теплохода 

60*3=180 км 

 

 

 

 

Answer 2

Calculation of Distance Covered by the Ship

To calculate the distance covered by the ship at a speed of 40 km/h, we can use the formula:

Distance = Speed × Time

Given that the ship travels at a speed of 40 km/h and covers a distance of 120 km, we can calculate the time taken using the formula:

Time = Distance / Speed

Substituting the given values: Time = 120 km / 40 km/h = 3 hours

So, the ship takes 3 hours to cover a distance of 120 km at a speed of 40 km/h.

Increased Speed and Distance Covered

Now, if the ship increases its speed by 20 km/h, we can calculate the distance it will cover in the same 3 hours.

The new speed is 40 km/h + 20 km/h = 60 km/h.

Using the same formula: Distance = Speed × Time

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 hours.

So, the ship will cover a distance of 180 km in the same time if it increases its speed by 20 km/h.
