A passenger car is driving from place a to place B, and a freight car is driving from place B to place a. the passenger car runs 30 kilometers past the midpoint and meets the freight car. It is known that the speed of the freight car is 62.5% of that of the passenger car. How many kilometers will the freight car travel to place a after meeting?
1: 62.5% = 8:5, (30 × 2) △ 8-5, = 60 △ 3, = 20 (km), 20 × 8 = 160 (km); a: after the meeting, the truck has to drive 160 km to reach Jiadi

On a map with a scale of 1:6000000, the distance between a and B is 15 cm. If an airplane flies at 800 km/
How many hours does it take to fly from place a to place B?
What is the actual distance between the two places
15 △ 1 / 6000000 = 90000000 (CM) = 900 (km)
Need to fly
900 △ 800 = 1.25 (hours)
On the map of China with a scale of 1 / 6000000, the distance between a and B is 17 cm. How many kilometers is the actual distance between the two places
If it is drawn on a map with a scale of 1 / 5000000, how many centimeters should it be drawn
want
Formula
Actual distance: 0.00017 / (1 / 6000000) = 1020 km
How many centimeters should be drawn: 102000000 * (1 / 5000000) = 20.4cm
The actual distance between land a and land B is 240 kilometers. How many centimeters should be drawn on a map with a scale of 1; 6000000
Should be drawn = 240 × 100000 △ 6000000 = 4cm
On a map with a scale of 1 ·: 6000000, the distance between a and B is 5cm. If you draw on a map with a scale of 1:24000000, the distance between a and B is 5cm
How long should I draw?
5 * 6000000 / 24000000 = 5 / 4 = 1.25cm
Therefore, it should be drawn on a map with a scale of 1:24000000, and 1.25cm should be drawn from land a to land B
If you don't understand, please ask, I wish you a happy study!
On the map with a scale of 1:6000000, the distance between a and B is 36cm. A plane flies from a to B, and it takes 9 hours to go back and forth
The round-trip speed ratio is 5:4. What's the round-trip speed of this plane
1:6000000=36:X
X=216000000
216000000 cm = 2160m
The speed ratio is 5:4 and the time ratio is 4:5
2160 × 5 / 9 = 1200 km
2160 × 4 / 9 = 960km
On the map with a scale of 1:6000000, it is measured that the distance between a and B is 18 cm. There are two cars traveling from the two places, 50 km each hour. How many hours later will they meet?
18x60=1080
1080/100=10.8
