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?

We use the formula of the direct rule of 3:

x = 90,000
90,000 babies are born in 2 hours.
