Question

Моторная лодка, двигаясь по течению, за 1,2 часа прошла 21,84 км. Найдите собственную скорость моторной лодки, если скорость течения равна 2,2 км/ч

Answer 1

Відповідь:16км/час

Покрокове пояснення:

V(лод и меня)=21,84/1,2=18,2км/час

V(меня)=18,2-2,2=16км/час

Answer 2

Problem Analysis

We are given that a motorboat traveled a distance of 21.84 km in 1.2 hours while moving with a current of 2.2 km/h. We need to find the speed of the motorboat.

Solution

To find the speed of the motorboat, we can use the formula:

Speed = Distance / Time

In this case, the distance traveled by the motorboat is 21.84 km and the time taken is 1.2 hours. Let's calculate the speed:

Speed = 21.84 km / 1.2 hours

Calculating this, we find:

Speed = 18.2 km/h

Therefore, the speed of the motorboat is 18.2 km/h.

Answer

The speed of the motorboat, when moving with a current of 2.2 km/h and traveling a distance of 21.84 km in 1.2 hours, is 18.2 km/h.
