Compound rule of three

In a custom clothing shop, $3$ thermal printing machines manage to print $120$ T-shirts working for $4$ hours. If due to an urgent order from a secondary school $5$ identical machines are started up, how many T-shirts will they be able to print in $6$ hours?

An animal shelter needs $480$ kg of feed to feed $40$ dogs for $30$ days. If the shelter receives a donation and increases its capacity to $60$ dogs, how many kilograms of feed will they need to feed them for $20$ days?

In a water recycling plant, $8$ identical treatment units filter $2400$ cubic metres of water over a period of $5$ days. How many cubic metres of water will $12$ treatment units filter if they run for $7$ days?

A group of $4$ travel content creators managed to edit $12$ videos for their channel working $6$ hours a day for a week. If $2$ more collaborators join the team next month and decide to work $8$ hours a day, how many videos will they be able to edit in the same period of time?

A courier company uses $8$ drones to deliver $160$ parcels in $4$ flight hours. If the company decides to increase its fleet to $10$ drones and wants to deliver $250$ parcels, how many total flight hours will the drones need to complete the task?

In an animal rescue centre, it has been calculated that $15$ bags of dry food of $20\text{ kg}$ each are sufficient to feed $40$ dogs for $12$ days. Due to a rescue campaign, the number of dogs increases by $20$ more animals. If the centre buys bags of $30\text{ kg}$ of the same food, how many bags will they need to feed all the dogs for $25$ days?

A video game server farm uses $8$ cooling units to maintain the optimal temperature for $120$ servers running for $24$ hours a day, with an electricity cost of $480\text{ €}$ a week. If the company decides to expand its capacity to $200$ servers and the price of electricity rises, so that the maximum allowed cost is $600\text{ €}$, for how many hours a day can the servers be switched on if the same $8$ cooling units are kept? (Assume that the cost is directly proportional to the number of servers and the hours of use).

In an electronics components factory, $5$ identical machines produce $2000$ processors running for $8$ hours a day. Due to an urgent order, the factory must deliver $3500$ processors in the same number of days. If $2$ more machines are started up, how many hours per day must all the machines run?

A group of $5$ identical taps takes $8$ hours to fill $3$ tanks of $600$ litres each. If we want to fill $4$ tanks of $900$ litres each in a maximum time of $10$ hours, how many taps with the same characteristics will we need to turn on? If the result is not an integer, explain the minimum number of taps we should install.
