In a company, a mechanic maintains four very important machines in a production process, which usually break down on average every 10 hours. This time between breakdowns has an exponential distribution. The mechanic spends on average 7 hours repairing a loom and its repair time also has an exponential distribution. Determine the average time a machine spends waiting for maintenance.
