To solve the problem, we need to convert the distance from feet to inches, since the speed of the ladybug is given in inches per second.
- We start with the distance: 10 feet.
- We know that 1 foot is equal to 12 inches.
To convert 10 feet to inches, we would multiply 10 feet by the conversion factor \(\frac{12 \text{ inches}}{1 \text{ foot}}\):
\[ 10 \text{ feet} \times \frac{12 \text{ inches}}{1 \text{ foot}} = 120 \text{ inches} \]
Now, let's examine the answer choices given:
A. Converting feet to inches by dividing 10 feet by \(\frac{12 \text{ inches}}{1 \text{ foot}}\)
B. Converting feet to inches by multiplying 11 feet by \(\frac{1 \text{ foot}}{12 \text{ inches}}\)
C. Converting feet to inches by multiplying 10 feet by 12
D. Converting feet to inches by multiplying 10 feet by \(\frac{12 \text{ inches}}{1 \text{ foot}}\)
The correct unit conversion that makes the most sense is: D. Converting feet to inches by multiplying 10 feet by \(\frac{12 \text{ inches}}{1 \text{ foot}}\)
This option correctly applies the conversion factor to convert feet into inches.
