Question

катер плыл 3 часа по течению реки и 4 часа против течения какое расстояние прошел катер за это время если собственна скорость катера х км ч а скорость течения реки m км ч

Answer 1

Х+м скорость по течению;х-м скорость против течения 3(х+м)+4(х-м)=3х+3м+4х-4м=7х-м

Answer 2

Calculating the Distance Traveled by the Boat

To calculate the distance traveled by the boat, we can use the formula: distance = speed * time

Given: - The boat traveled 3 hours downstream at a speed of (x + m) km/h. - The boat traveled 4 hours upstream at a speed of (x - m) km/h.

Let's calculate the distance traveled in each direction and then find the total distance traveled.

Distance Traveled Downstream

The distance traveled downstream can be calculated using the formula: distance downstream = (x + m) * 3

Distance Traveled Upstream

The distance traveled upstream can be calculated using the formula: distance upstream = (x - m) * 4

Total Distance Traveled

The total distance traveled by the boat can be calculated by adding the distances traveled downstream and upstream: total distance = distance downstream + distance upstream

Let's calculate the total distance traveled by the boat.
