KS2 Primary Maths Age 9-13 - Geometry: Scale Drawings - Explained

The video tutorial explains how to use a map scale where 1 cm represents 20 km to find the distance between two cities that are 250 km apart. It involves dividing 250 by 20 to convert kilometers to centimeters on the map, resulting in 12.5 cm. The tutorial also covers handling remainders in division and the marking scheme for the problem.

If 1 centimeter on a map represents 20 kilometers, how many kilometers does 5 centimeters represent?

• 100 kilometers

• 50 kilometers

• 250 kilometers

• 200 kilometers

What is the first step in calculating the map distance for 250 kilometers?

• Add 250 to 20

• Divide 250 by 20

• Subtract 20 from 250

• Multiply 250 by 20

When dividing 250 by 20, what is the remainder after the first division step?

• 20

• 15

• 10

• 5

How many times does 20 go into 100 when calculating the decimal part of the division?

• 3 times

• 4 times

• 6 times

• 5 times

What is the final map distance in centimeters for 250 kilometers?

• 12.5 centimeters

• 11.5 centimeters

• 10.5 centimeters

• 13.5 centimeters
