On a map with the scale of 1: 7500000, the distance between Party A and Party B is 10 cm, and the distance from Beijing to Hangzhou is 1250 km. On a map of China with the scale of 1: 2500000, what should be the distance between the two places? There is a trapezoidal experimental field. On the map with the scale of 1:2000, the upper bottom is 2.5 cm, the lower bottom is 4 cm and the height is 2 cm. What is the actual area of the experimental field? The science and education building is150m in length, 25cm in design plane and15cm in width. What is the scale of the building plane? How many square meters does this building cover? A right-angled triangular steel plate is drawn on the drawing with the scale of 1/200. The two right-angled sides are 5.4 cm long, and the ratio of their lengths is 5: 4. What is the actual area of the steel plate? Draw a rectangular plot with the length-width ratio of 5: 3 on the map with the scale of 1/500, and the rectangular perimeter is 32 cm. What is the actual area of rectangular land? On the map of 3000000 with the scale of 1, the distance between a and b is 4.5 cm. How many hours does it take for a car to drive from A to B at a speed of 60 kilometers per hour? Going out for sightseeing, we often take pictures. If Xiao Liang's photos show that the Tiananmen Gate Tower is only 29.5mm long, the actual Tiananmen Gate Tower is118m long. What's the scale of this photo? On the map with the scale of 1: 3000000, the total length of the Yangtze River is 2 1 cm. How many kilometers is the actual length of the Yangtze River? Part A is10m long, which is drawn on Figure A, and part B is 7m long, which is drawn on Figure B. The two parts are the same in length. The scale of Figure A is 1: 100. What is the scale of Figure B? Two people, A and B, walked past A and B at the same time. A It takes six hours. When they met, the distance traveled was 3: 2. At this time, A travels more than B18km. How many kilometers does B travel per hour? The distance between Party A and Party B is 360 kilometers, and the actual distance measured on a map is 6 cm. What's the scale of this map? On the map with the scale of 1: 3000000, the route between A and B is 4.5 cm long. On the map with the scale of 1:25000, how long is the route between A and B? The actual distance from Beijing to Guangzhou is about 2400 kilometers. According to the map, the distance between Beijing and Guangzhou is 8 cm. What's the scale of this map?
