Question

Теплоход на подводных крыльях прошёл расстояние между пристанями со средней скоростью 60 км/ч за 2,5 ч.За сколько времени пройдёт это расстояние теплоход,если будет идти со скоростью 50 км/ч?

Answer 1

Вычисляем расстояние:
60 * 2,5 = 150 км.
Вычисляем время:
150 / 50 = 3 часа
Ответ: 3

Answer 2

(60+2,5+50):2,5=8,5+50=13,5

Answer 3

Calculation of Time Taken to Travel the Distance

To calculate the time taken to travel the distance between the two ports, we can use the formula:

Time = Distance / Speed

Given that the distance between the ports is covered at an average speed of 60 km/h in 2.5 hours, we can calculate the distance using the formula:

Distance = Speed x Time

Let's calculate the distance first:

Distance = 60 km/h x 2.5 hours = 150 km.

Now, we can calculate the time taken to travel the distance at a speed of 50 km/h using the formula:

Time = Distance / Speed

Time = 150 km / 50 km/h = 3 hours.

Therefore, if the ship travels at a speed of 50 km/h, it will take 3 hours to cover the distance between the ports
