Jiangsu education printing plate sixth grade mathematics problem
1. The distance on the map divided by the scale = actual distance: 70 ÷1:200000 =140000000 (cm) The actual distance multiplied by the scale equals the distance on the map:140000000×/kloc-0.

0 20 40 (meters) Every short distance can be calculated first ~ 1: 2000 One centimeter equals 20 meters.

Fill in the blanks: ┖-┻-┛.

2. First, divide the distance on the map by the scale to find the actual distance. Because the ratio of A and B to station C is 7: 5, but it takes 0.6 hours from city B to station C, the sum of the ratios of A and B is multiplied by the actual distance of 65438+5/02 to calculate the distance from B to C, and then the unit is converted (1km is equal to 1000000).

Formula: 2.4÷ 1:3000000=7200000 (cm) 7200000× 12 = 3000000 (cm).

3,000,000 cm =30 km 30÷0.6=50 (km/h)
