Answer:
19 seconds.
Step-by-step explanation:
Given that the clock was exactly on time at 7am, and at 1pm the clock was 228 seconds late, to determine, at that rate, how slow was the clock half an hour, the following calculation must be performed:
1 PM = 13:00
13 - 7 = 6
228/6 = 38
38/2 = 19
Thus, every half hour the clock is delayed 19 seconds.

Answer:
10
Step-by-step explanation:
T= total played
e= # evenings played
m= # minutes played
Total equals number of evenings played multiplied by number of minutes plated per evening.
EQUATION:
t=e * m
EQUATION (if 30 minutes per evening):
t=30e
Example:
3 nights, 30 minutes played
t= 3 * 30
t=90 minutes total played
