Math problem: on a map with the following scale, the distance between station a and station B is 16 cm On a map marked with the following scale, the distance between stations a and B on the railway line is 16 cm. Passenger cars and freight cars leave from stations a and B at the same time. Passenger cars travel 60 km per hour, and trains 40 km per hour. How many hours later do the two cars meet? 0-50-100-150-200 km Detailed process, help!

Your ratio seems to be 1cm = actual 50km, that is to say, between a and B is 16 * 50 = 800km
The meeting time t = 800 / (60 + 40) = 8 hours

The distance between cities a and B measured on a 1:400000 map is 5 cm longer than that measured on a 1:1500000 map
What is the actual distance between a and B? (for example, the process of solving the equation should be written clearly)

The actual distance between the two cities remains unchanged
The actual distance between the two cities is x cm
1/400000x-1/1500000x=5
11/6000000x=5
x=5×6000000/11
x=300 00000/11
x≈2727272.7
272.7cm ≈ 27.27km
A: the actual distance between the two cities is 27.27 km
I think there is something wrong with the data. If the second scale is 1:500000, it will be easier to calculate
5÷（1/400000-1/500000）
=5÷1/20 00000
=1 million (CM)
=100 (km)

The scale of a map is 0-50-100-150 km. On this map, the length of railway between a and B is 3.2 cm, and the actual distance between the two places is ()? 1000

160 km

On the scale of 1:2000000, the distance between the two cities is 6cm. What is the actual distance?

6 △ 12000000, = 6 × 2000000, = 12000000 (CM), 12000000 cm = 120km; a: the actual distance between the two cities is 120km
