Question

Расстояние между причалами 24 километра Сколько времени потратит моторная лодка на путь от одного причала до другого и обратно если собственная скорость лодки 10 километров в час скорость течения 2 километра в час

Answer 1

S=24км
U лодки=10км/ч
U течения=2км/ч
1)10+2=12(км/ч) скорость по течению
2)24:12=2(ч) время потраченное на путь от одно го причала к другому
3)24:8=3(ч) время потраченное на обратный путь
4)2+3=5(ч) всего
Ответ: 5 часов

Answer 2

Calculation of Time for Motorboat Journey

To calculate the time it will take for a motorboat to travel from one pier to another and back, we need to consider the distance between the piers, the speed of the motorboat, and the speed of the current.

Given information: - Distance between the piers: 24 kilometers - Speed of the motorboat: 10 kilometers per hour - Speed of the current: 2 kilometers per hour

To calculate the time for the motorboat journey, we can use the formula:

Time = Distance / (Speed of Motorboat + Speed of Current)

Substituting the given values into the formula, we get:

Time = 24 kilometers / (10 kilometers per hour + 2 kilometers per hour)

Simplifying the equation, we have:

Time = 24 kilometers / 12 kilometers per hour

Therefore, the time it will take for the motorboat to travel from one pier to another and back is 2 hours.

Please note that the calculation assumes a constant speed throughout the journey and does not account for factors such as acceleration, deceleration, or any stops along the way.
