Question

расстояние между двумя пристанями теплоход прошел за 3 часа, двигаясь со скоростью 32км/ ч. обратно он прошел это расстояние за 4ч.. с какой скоростью шел теплоход в обратном направлении?

Answer 1

1)3*32=96КМ-РАССТОЯНИЕ МЕЖДУ ПРИСТАНЯМИ.

2)96:4=24КМ/Ч-СКОРОСТЬ НА ОБРАТНОМ ПУТИ.

Answer 2

Calculation of the Speed of the Boat in the Opposite Direction

To calculate the speed of the boat in the opposite direction, we can use the formula:

Speed = Distance / Time

Let's denote the distance between the two piers as 'd'. According to the given information, the boat traveled this distance in 3 hours at a speed of 32 km/h. Therefore, we can write the equation:

32 km/h = d / 3 hours

Similarly, when the boat traveled back from the second pier to the first pier, it covered the same distance 'd' in 4 hours. So we have:

Speed = d / 4 hours

To find the speed of the boat in the opposite direction, we need to solve these two equations simultaneously.

Solving the Equations

To solve the equations, we can use a method called substitution. We can rearrange the first equation to solve for 'd':

d = 32 km/h * 3 hours

Substituting this value of 'd' into the second equation, we get:

Speed = (32 km/h * 3 hours) / 4 hours

Simplifying the equation, we have:

Speed = 24 km/h

Therefore, the speed of the boat in the opposite direction is 24 km/h.
