Question

Скорость теплохода по течению реки -36,5 км/ч.Скорость течения реки-2,5 км/ч.Какое расстояние пройдёт теплоход против течения реки за 4 ч?

Answer 1

Скорость против течения - 36,5 - 2,5 = 34 км/ч 34*4 = 136 км

Answer 2

Calculating the Distance Traveled Against the River Current

To calculate the distance traveled by the boat against the river current, we can use the formula:

Distance = (Speed of the boat in still water - Speed of the river current) * Time

Given: - Speed of the boat in still water = 36.5 km/h - Speed of the river current = 2.5 km/h - Time = 4 hours

Using the given values, we can calculate the distance traveled by the boat against the river current.

Calculation

Distance = (36.5 - 2.5) * 4

Distance = 34 * 4

Distance = 136 km

Therefore, the boat will travel a distance of 136 kilometers against the river current in 4 hours.
