Answer:

Mary reached the airport in 40 minutes

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Time it takes John to go from home to the train station = 30 minutes

Time it takes John to go from the train station to the airport = 55 minutes

Mary left 25 minutes later and reached the airport 20 minutes earlier than John

2. How long did it take Mary to get to the airport?

Total time it takes John to reach the airport = Time it takes John to go from home to the train station + Time it takes John to go from the train station to the airport

Total time it takes John to reach the airport = 30 + 55

Total time it takes John to reach the airport = 85 minutes

Now, let's calculate the time it takes Mary to reach the airport, this way:

Total time it takes John to reach the airport - minutes Mary left later - minutes Mary got to the airport earlier than John

85 - 25 - 20 = 85 - 45 = 40

Mary reached the airport in 40 minutes
