You divided cm³ by litres, that's where you went wrong.

The volume of the cilinder is 753982 cm³ which is 753.982 litres

To fill it takes 753.982/0.2 seconds ≈ 3769.9 seconds.

In an hour there are 60*60=3600 seconds, so it takes slightly more than one hour.

But as you can see you were very close. It helps to always write the unit with any number.

Answer:

At 6 p.m., the number of cars in a parking lot is 120

Step-by-step explanation:

At 1 p.m., the number of cars in a parking lot is 78.

Given,

$A_n=78\cdot 1.09^n$

Note that

$A_0=78\cdot 1.09^0=78\cdot 1=78$

So, 1 p.m. goes for n = 0, then

6 p.m. goes for n = 5

Thus,

$A_5=78\cdot 1.09^5\approx 120$
