Ответ: 80p, или 82,7p

Answer 2

To find the cost of a call lasting 5 minutes 20 seconds, we need to calculate the cost per minute and then multiply it by the total number of minutes.

Let's first calculate the cost per minute: The cost of a call lasting 3 minutes 30 seconds is 52.5p. To convert this to the cost per minute, we can divide the total cost by the number of minutes: 52.5p / 3.5 minutes = 15p per minute

Now we can calculate the cost of a call lasting 5 minutes 20 seconds: The call duration is 5 minutes 20 seconds, which is equivalent to 5.33 minutes (since there are 60 seconds in a minute). To calculate the cost, we multiply the number of minutes by the cost per minute: 5.33 minutes * 15p per minute = 79.95p

Therefore, the cost of a call lasting 5 minutes 20 seconds is approximately 79.95p.
