Beijing and Tianjin are about 120 kilometers apart. How many centimeters is the distance on the 1:600000 map? The distance between a and B is 15 cm. How many kilometers is the actual distance between a and B?

Beijing and Tianjin are about 120 kilometers apart. How many centimeters is the distance on the 1:600000 map? The distance between a and B is 15 cm. How many kilometers is the actual distance between a and B?


120 km = 12000000 cm, 12000000 × 1600000 = 20 (CM); 15 ÷ 1600000 = 9000000 (CM) = 90 (km). A: the distance on a map with a scale of 1:600000 is about 20 cm, and the actual distance between a and B is 90 km



The actual distance between Beijing and Nanjing is about 900 km. On the 1:6000000 map, the distance between Beijing and Nanjing is___ Cm


900km = 90000000 cm 90000000 × 16000000 = 15 (CM) answer: the distance between Beijing and Nanjing is 15cm. So the answer is: 15



The distance between Beijing and Nanjing measured on a 1:6000000 map is 18cm
How many hours does it take for a plane to fly from Beijing to Nanjing at the speed of 750 kilometers per hour?


18 ÷ (1 / 6000000) = 108000000cm = 1080000 M = 1080km, the distance between Beijing and Nanjing
1080 △ 750 = 1.44 hours
About 1.44 hours, that is about 87 minutes



The scale of a map is 1:50000. How many meters does 3cm on the map represent the actual distance?


1500 meters



A map with the original scale of 1:30000 is now redrawn with the scale of 1:50000. How many centimeters should be drawn in the new map for the distance of 4.5cm in the original map?


4.5 x 30000 △ 50000 = 2.7 cm



The scale of a map is 1 / 300000, and 6cm on the map indicates the actual distance of kilometers
If the actual distance between a and B is 150 kilometers, how many centimeters should we draw on the map


6x300000 △ 100000 = 18km
150x100000 △ 300000 = 50cm



On a map with a scale of 1:100000, the distance is 12cm. If the scale of 1:300000 is used to represent the distance on the map, how many cm is it


4



For a map, 20cm on the map represents the actual distance of 10km, calculate the scale of the map, and then rewrite the numerical scale into the line scale


10km = 1000000cm, scale = 20:1000000 = 1:50000. A: the scale of this map is 1:50000, and the scale of line segment is



Judgment: 1. The distance on a map is 10 cm, which means the actual distance is 2 mm. The scale of this map is 50:1
2. The scale of a picture is 1:8000, which means that the actual distance is 8000 times of the distance on the picture


1. Correct, 10 cm = 100 mm, the distance on the map is more than the actual distance, 100:2 = 50:1
2. Correct, the scale is equal to the distance on the map than the actual distance, so correct



The scale of a map is 1:5 million, and the actual area of 1 square centimeter of land on the map is 2
The final unit is square meters


The side length of a small square of 1 square centimeter is 1 centimeter
Actual side length: 1 ÷ (1:5 million)
=1÷1/5000000
=5000000 cm
=50000 meters
Actual area: 50000 * 50000 = 2500000000 square meters
