On a map with a scale of 5000000 / 1, the distance between a and B is 8cm; on another map with a scale of 1:4000000, the distance between a and B is 8cm How many centimeters are there between a and B?

On a map with a scale of 5000000 / 1, the distance between a and B is 8cm; on another map with a scale of 1:4000000, the distance between a and B is 8cm How many centimeters are there between a and B?

Should be drawn = 8 × 5000000 △ 4000000 = 10cm

On a map with a scale of 1:5000000, the distance between the two cities is 8 cm. If you draw it on a map with a scale of 1:2000000, how many cm is the distance between the two cities
What's the formula

It's 20 centimeters
Children study hard
Eight times 5000000 divided by 2000000 equals 20

On a map with a scale of 1:4000000, the distance between a and B is 18cm. A and B cars drive from a and B at the same time
Out, a travels 42 kilometers per hour, B travels 48 kilometers per hour. How many hours later do the two cars meet?

Distance = 4000000 × 18 ﹣ 100 ﹣ 1000 = 720km;
Time = 720 (42 + 48) = 8 hours;
If you don't understand this question, you can ask,

On a map with a scale of 14000000, the distance between a and B is 35cm. If the two places are drawn on a map with a scale of 1:7000000, how long should they be drawn?

35 △ 14000000 × 17000000, = 35 × 4000000 × 17000000, = 20 (CM); a: if you draw these two places on a map with a scale of 1:7000000, you should draw 20 cm
