Question

Мастер-жестянщик может отремонтировать разбитую автомашину за 12,5 часа, а его ученик выполняет 0,03 этой же работы за 1,5 часа.Сколько времени им понадобится для совестного выполнения этой работы.

Answer 1

Calculation of Time Required for the Job

To calculate the time required for the master-tinsmith and his apprentice to complete the job, we need to consider their individual rates of work.

According to the information provided: - The master-tinsmith can repair a broken car in 12.5 hours. - The apprentice can complete 0.03 of the same job in 1.5 hours.

To find the time required for both of them to complete the job together, we can set up the following equation:

Time taken by the master-tinsmith + Time taken by the apprentice = Total time taken

Let's calculate the time required:

Time taken by the master-tinsmith = 12.5 hours

Time taken by the apprentice = 0.03 * 1.5 hours

Total time taken = Time taken by the master-tinsmith + Time taken by the apprentice

Now we can substitute the values and calculate the total time required.
