Final answer:
The reloj despertador will be delayed by 480 seconds or 8 minutes in 24 hours.
Step-by-step explanation:
The reloj despertador is causing a delay of 20 seconds per hour. To find out how much it will be delayed in 24 hours, we can multiply the delay per hour (20 seconds) by the number of hours (24).
So, the reloj despertador will be delayed by 480 seconds (20 seconds/hour * 24 hours). We can convert this to minutes by dividing by 60, which gives us 8 minutes.
Therefore, the reloj despertador will be delayed by 480 seconds or 8 minutes in 24 hours.
