To determine the time it takes for a ladybug traveling at a speed of 3 inches per second to crawl up a 10-foot section of wall, we need to ensure both distance and speed are expressed in the same units. Since the ladybug's speed is given in inches per second, we should convert the 10 feet to inches.
The correct unit conversion to use is:
- Converting feet to inches by multiplying 10 feet by \( \frac{12 \text{ inches}}{1 \text{ foot}} \).
This conversion means you multiply the number of feet (10) by the conversion factor to get the equivalent distance in inches.
Thus, the best response is:
Converting feet to inches by multiplying 10 feet by \( \frac{12 \text{ inches}}{1 \text{ foot}} \).
