Question

Расстояние между пристанями катер прошёл со скоростью 40км/ч за 2ч а обратный путь - за 5 ч. С какой скоростью катер шёл на обратном пути?

Answer 1

40*5=200(км)катер проедет на обратном
 пути

Answer 2

40:2=20км 20:5=4км/ч

Answer 3

Calculation of Speed

To find the speed of the boat on the return trip, we can use the formula:

Speed = Distance / Time

Let's calculate the distance and time for each leg of the journey.

1. For the forward trip: - Speed: 40 km/h - Time: 2 hours - Distance = Speed * Time = 40 km/h * 2 hours = 80 km

2. For the return trip: - Time: 5 hours - Distance = Speed * Time = Unknown

Now, let's calculate the speed of the boat on the return trip.

Using the formula, we can rearrange it to solve for speed:

Speed = Distance / Time

Speed = 80 km / 5 hours = 16 km/h

Therefore, the speed of the boat on the return trip was 16 km/h.
