Answer:
90,000
Step-by-step explanation:
Let's calculate how many seconds we have in two hours.
In one hour we have 60 minutes, so in 2 hours we have 2*60 = 120 minutes.
In one minute we have 60 seconds, so in 120 minutes we have 120*60 = 7,200 seconds.
Now we can use a direct rule of 3. If in 0.08 seconds 1 baby is born, how many babies will be born in 7,200 seconds?
[tex]\text{0.08 seconds} -\!\!\!-\!\!\!- \text{1 babies}\\ \text{7,200 seconds} -\!\!\!-\!\!\!- \text{x babies}[/tex]
We use the formula of the direct rule of 3:
[tex]x = \frac {7,200 * 1}{0.08} \\ \\ x = \frac {7,200}{0.08}\\ \\[/tex]
x = 90,000
90,000 babies are born in 2 hours.
