Answer 1

To convert kilometers to centimeters, we can use the metric conversions:

1 kilometer is equal to 1,000 meters, and 1 meter is equal to 100 centimeters. Therefore, 1 kilometer equals 100,000 centimeters (1,000 meters × 100 centimeters/meter).

To find the distance Penelope drove in centimeters, we can multiply the distance in kilometers (27 km) by 100,000 cm/km.

So the expression we need is:

\[ 27 \times 100,000 \]

Thus, the correct answer is:

**StartFraction 27 times 100,000 EndFraction**
