If a subway car passes 3 stations every 10 minutes, how many stations will it pass in one hour?

If a subway car passes 3 stations every 10 minutes, how many stations will it pass in one hour?

• A. 15
• B. 18
• C. 20
• D. 30

Answer: (B)

To determine how many stations the subway car will pass in one hour, we first need to establish the rate at which it passes stations. The problem states that the subway car passes 3 stations every 10 minutes. To find out how many stations it passes in an hour, we can start by calculating how many 10-minute intervals are there in one hour (60 minutes). Since an hour has 60 minutes, we divide 60 by 10: \[ 60 \div 10 = 6 \] This indicates there are 6 intervals of 10 minutes in one hour. Since the subway passes 3 stations in each of these intervals, we can calculate the total number of stations passed in one hour by multiplying the number of intervals by the number of stations passed per interval: \[ 6 \times 3 = 18 \] Thus, the subway car will pass 18 stations in one hour, making that the correct answer.

To find out how many stations it passes in an hour, we can start by calculating how many 10-minute intervals are there in one hour (60 minutes).

Since an hour has 60 minutes, we divide 60 by 10:

[ 60 \div 10 = 6 ]

This indicates there are 6 intervals of 10 minutes in one hour. Since the subway passes 3 stations in each of these intervals, we can calculate the total number of stations passed in one hour by multiplying the number of intervals by the number of stations passed per interval:

[ 6 \times 3 = 18 ]

Thus, the subway car will pass 18 stations in one hour, making that the correct answer.
