At 9:00 a.m. marsha found a parking meter that still had 5 minute until it expired. She quickly put a quarter, 1dime, and a nickel into the meter and went to her meeting. If 5¢ buys 15 minute of parking time, at what time will the meter expired
To find out at what time the meter will expire, we need to determine how many minutes the coins Marsha put in will purchase.
First, let's determine the value of the coins Marsha put in. She inserted a quarter (25 cents), a dime (10 cents), and a nickel (5 cents). If we add these values together, we get a total of 40 cents (25 + 10 + 5 = 40).
We also know that 5 cents will buy 15 minutes of parking time. So, to find out how many minutes 40 cents will buy, we can set up a proportion:
5 cents -> 15 minutes
40 cents -> x minutes
To solve this proportion, we can cross-multiply and divide:
5 * x = 40 * 15
5x = 600
x = 120
Therefore, the 40 cents that Marsha put in will buy her 120 minutes of parking time.
Since she found the parking meter at 9:00 a.m. and the meter had 5 minutes until it expired, we can add 120 minutes to 9:00 a.m.:
9:00 a.m. + 120 minutes = 11:00 a.m.
Therefore, the meter will expire at 11:00 a.m.
