A mobile phone company charges 5 cents for each 20 second call. How much will it charge a 2 minute call?
1 minute = 60 seconds
(120 / 20) * 0.05 = $_______
To calculate the cost of a 2-minute call, we need to convert the call duration from minutes to seconds and then divide it by 20.
First, let's convert 2 minutes to seconds:
2 minutes * 60 seconds/minute = 120 seconds.
Next, we divide the call duration by the duration per charge, which is 20 seconds:
120 seconds / 20 seconds = 6 charges.
Now, we know that each charge costs 5 cents. So, we multiply the number of charges by the cost per charge:
6 charges * 5 cents/charge = 30 cents.
Therefore, a 2-minute call will cost 30 cents.
