Question: If a bus leaves every 15 minutes starting from 8:00 AM, what time will the 5th bus leave?

Options:

Correct Answer: 8:45 AM

Solution:

The 5th bus will leave at 8:00 AM + 4 * 15 minutes = 8:45 AM.

If a bus leaves every 15 minutes starting from 8:00 AM, what time will the 5th bus leave?

If a bus leaves every 15 minutes starting from 8:00 AM, what time will the 5th bus leave?

Step 1: Identify the starting time when the first bus leaves, which is 8:00 AM.
Step 2: Determine the interval at which the buses leave, which is every 15 minutes.
Step 3: To find the time of the 5th bus, we need to calculate how many 15-minute intervals there are before the 5th bus. Since the first bus is the 1st, the 5th bus will have 4 intervals before it.
Step 4: Calculate the total time for 4 intervals of 15 minutes: 4 * 15 minutes = 60 minutes.
Step 5: Add the 60 minutes to the starting time of 8:00 AM. 8:00 AM + 60 minutes = 9:00 AM.
Step 6: Therefore, the 5th bus will leave at 9:00 AM.
