In the picture, 1 centimeter equals an actual distance of 20 centimeters. According to this information, how far in centimeters did the apple actually fall from Position S to Position T?
Understand the Problem
The question asks to calculate the actual distance the apple fell from position S to T, given that 1 cm in the picture equals 20 cm in real distance. We can use the scale provided to determine the distance between positions S and T in the picture, then convert the distance to centimeters using the scale provided.
Answer
90 cm
Answer for screen readers
C. 90 cm
Steps to Solve
- Measure the scale in the picture
Using a ruler, measure the length of the $20 \text{ cm}$ scale provided in the picture. It measures $1 \text{ cm}$. 2. Measure the distance between position S and T in the picture
Using a ruler, measure the distance between position S and position T. It measures $4.5 \text{ cm}$. 3. Convert the measured distance to the actual distance
Since $1 \text{ cm}$ in the picture represents $20 \text{ cm}$ in reality, multiply the measured distance between S and T by 20 to get the actual distance:
$4.5 \text{ cm} \times 20 = 90 \text{ cm}$
C. 90 cm
More Information
The problem involves using a scale factor to convert a measurement on a picture to a real-world measurement.
Tips
A common mistake is to misread the ruler or miscalculate the multiplication. Ensure you are precise with your measurements and double-check your arithmetic.
