Question

Лодка прошла 48 км за 3 часа против течения и 2 часа по течению. Если скорость воды 2 км / ч, найдите скорость лодки.

Answer 1

1.) (48-2•3+2•2):5=7,6 (км/ч)
Ответ:скорость лодки 7,6 км/ч

Answer 2

Calculation of Boat Speed

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

Speed = Distance / Time

Given that the boat traveled 48 km in 3 hours against the current and 2 hours with the current, we can calculate the speed of the boat.

1. Against the current: - Distance = 48 km - Time = 3 hours

2. With the current: - Distance = 48 km - Time = 2 hours

Let's calculate the speed of the boat in each case:

1. Against the current: - Speed = 48 km / 3 hours = 16 km/h.

2. With the current: - Speed = 48 km / 2 hours = 24 km/h.

Therefore, the speed of the boat is 16 km/h against the current and 24 km/h with the current.
