Answer:
The number of times signal a beeps in 1 hour = 144 times
The number of times signal b beeps in 1 hour = 120 times
The number of times signal c beeps in 1 hour = 36 times
The number of times three signals bee in one hour = 12 times
Step-by-step explanation:
The given parameters are;
The period for each signals beep are;
Signal a beeps every 25 seconds
Signal b beeps every 30 seconds
Signal c beeps every 100 seconds
Therefore, in one hour, signal a will beep 1× 60 × 60/25 = 3600/25 = 144 times
In one hour, signal b will beep 1×60×60/30 = 3600/30 = 120 times
In one hour, signal c will beep 1×60×60/100 = 3600/100 = 36 times
Therefore, we have;
The number of times signal a beeps in 1 hour = 144 times
The number of times signal b beeps in 1 hour = 120 times
The number of times signal c beeps in 1 hour = 36 times
From Excel, we can see that the three signals beep the same time at 300, 600, 900, 1200, 1500, 1800, 2100, 2400, 2700, 3000, 3300, and 3600
The number of times three signals bee in one hour = 12 times
signal a beeps every 25 seconds
signal b beeps every 30 seconds
signal c beeps every 100 seconds.
Answer to the above questions is 300,600,900 if the signal beep at the same time 12 times
Explanation to the above questions
- One hour contains 3600 seconds
- Signal a beep 3600/25=144
- Signal b beep 3600/30=120
- signal c beep 3600/100=36
- At the same time all the signal beep than 144+120+36=300
we conclude that it will beep 12 times because 300,600,900,1200,1500,1800,2100,2400,2700,3000,3300,3600
