Question

Один трубоукладчик уложил 192 м труб за 24 часа работы другой уложил 220 м труб за 20 часов работы Какова производительность каждого трубоукладчика чтобы уложить 190 м труб оба трубоукладчика Запусти летний напряжение с двух концов участка Через сколько закончит работу

Answer 1

192 : 24 = 8 (м/ч) - производительность 1 трубоукладчика   
220 : 20 = 11 (м/ч) - производительность 2 трубоукладчика8 + 11 = 19 (м/ч) - опроизводительность190 : 19 = 10 )ч) - закончат работу

Answer 2

Calculating Pipe Layer Productivity

To calculate the productivity of each pipe layer, we can use the formula:

Productivity = Total length of pipe laid / Time taken

Let's calculate the productivity of each pipe layer using the given information.

For the first pipe layer: Productivity = 192 m / 24 hours = 8 m/hour For the second pipe layer: Productivity = 220 m / 20 hours = 11 m/hour

Time to Complete the Work

To find out when both pipe layers will finish laying 190 m of pipe, we can use the formula:

Time = Total length of pipe to be laid / Combined productivity of both pipe layers

Let's calculate the time it will take for both pipe layers to finish laying 190 m of pipe.

Combined productivity of both pipe layers = 8 m/hour + 11 m/hour = 19 m/hour

Time = 190 m / 19 m/hour = 10 hours

Therefore, both pipe layers will finish laying 190 m of pipe in 10 hours.

Running Voltage at Both Ends

It seems there might be a mix-up in the question. It mentions running voltage at both ends, which doesn't seem to be related to the pipe laying scenario. If you have a specific question about running voltage or any other topic, feel free to ask!
