Answer 3

To solve this problem, we need to perform the addition and subtraction of the given time durations.

Addition:

8 hours 24 minutes 15 seconds

• 2 hours 48 minutes 52 seconds = 11 hours 13 minutes 7 seconds

Subtraction:

9 meters 4 decimeters 4 millimeters

• 7 meters 9 centimeters 6 millimeters

We need to convert the units of the lengths to the same unit before we can subtract them. Let's convert everything to millimeters:

9 meters = 9000 millimeters 4 decimeters = 40 millimeters Total length = 9040 millimeters

7 meters = 7000 millimeters 9 centimeters = 90 millimeters 6 millimeters Total length = 7096 millimeters

Now we can subtract:

9040 millimeters - 7096 millimeters = 1944 millimeters

Therefore, the final answer is:

11 hours 13 minutes 7 seconds

• 9 meters 4 decimeters 4 millimeters

• 7 meters 9 centimeters 6 millimeters = 11 hours 13 minutes 7 seconds - 1 meter 944 millimeters = 11 hours 13 minutes 7 seconds - 1 hour 59 minutes 4 seconds = 9 hours 14 minutes 3 seconds.

So the final answer is 9 hours 14 minutes 3 seconds.
