Finding Distance with Scale Classwork

What is the purpose of using a scale to find unknown distances?

• To compare known distances with unknown distances on a map or diagram.

• To determine the temperature of an object.

• To calculate the speed of an object.

• To measure the weight of an object.

When finding the actual distance using a scale, what should you do?

• Use a ruler to measure the distance on the scale.

• Convert the measured distance on the scale using the scale ratio.

• Multiply the measured distance on the scale by the scale ratio.

• Divide the measured distance on the scale by the scale ratio.

What is the formula to find the actual distance using a scale?

• Actual distance = Measured distance x Scale factor

• Actual distance = Measured distance - Scale factor

• Actual distance = Measured distance / Scale factor

• Actual distance = Measured distance + Scale factor
