Answer 3

Let's break down the expression step by step:

First, let's add the two lengths: 15 cm 3 mm and 17 cm 8 mm. 15 cm 3 mm + 17 cm 8 mm = (15 cm + 17 cm) + (3 mm + 8 mm) = 32 cm + 11 mm.

Now, let's convert mm to cm for easier calculation: 11 mm = 1.1 cm.

Now we have: 32 cm + 1.1 cm = 33.1 cm.

Next, let's multiply the result by 3: 33.1 cm * 3 = 99.3 cm.

Moving on to the next part: 3 hours 15 minutes is equivalent to 3.25 hours.

Now, let's multiply 3.25 hours by 3: 3.25 hours * 3 = 9.75 hours.

Finally, let's multiply 9.75 hours by 2: 9.75 hours * 2 = 19.5 hours.

Therefore, the final result is 99.3 cm and 19.5 hours.
