Question

ПРОШУ ПОМОГИТЕ!!! КРАТКУЮ ЗАПИСЬ НАПИШИТЕ!! СО СЛОВАМИ: СКОРОСТЬ, ВРЕМЯ, РАССТОЯНИЕ!! ПРОШУ!!! КАК МОЖНО БЫСТРЕЕ!!!! Моторная лодка прошла по течению реки 5 ч со скоростью 24 км\ч. На обратный путь она затратила на 1 час больше времени. Чему равна скорость моторной лодки против течения реки?

Answer 1

1)1+5=6(км ч)                                                                                                    2)24:6=4(км ч)Ответ: S моторной лодки=4 км ч

Answer 2

24*5=120 км-прошла лодка по течению
5+1=6 ч затратила на обратный путь
120/6=20 км/ч скорость против течения

Answer 3

Speed, Time, and Distance Calculation

To calculate the speed of the motorboat against the current of the river, we need to determine the distance traveled and the time taken for the return trip.

Given information: - The motorboat traveled downstream with a speed of 24 km/h for 5 hours. - The motorboat took 1 hour longer for the return trip.

Let's calculate the distance traveled downstream and the time taken for the return trip.

Distance traveled downstream: The distance traveled downstream can be calculated using the formula: distance = speed × time.

The speed of the motorboat downstream is 24 km/h, and the time taken is 5 hours. So, the distance traveled downstream is 24 km/h × 5 hours = 120 km.

Time taken for the return trip: The time taken for the return trip is 1 hour longer than the time taken for the downstream trip. So, the time taken for the return trip is 5 hours + 1 hour = 6 hours.

Now, we have the distance traveled downstream (120 km) and the time taken for the return trip (6 hours). We can calculate the speed of the motorboat against the current of the river using the formula: speed = distance / time.

Speed of the motorboat against the current: The speed of the motorboat against the current can be calculated as follows: speed = distance / time = 120 km / 6 hours = 20 km/h.

Therefore, the speed of the motorboat against the current of the river is 20 km/h.
