When freight cars arrive at 25 o'clock, passenger cars have already traveled 45 kilometers. How many kilometers is the distance between the two places?

25:45 = 1:2, 60 × 12 ﹣ 110, = 30 ﹣ 110, = 300 (km). A: the distance between AB and ab is 300 km

On the map marked with 1:4000000, it is measured that the distance between a and B is 12cm. A passenger car and a freight car run from a and B at the same time
It will meet in 6 hours. It is known that the speed ratio of bus to truck is 5:3,

On the map marked with 1:4000000, the distance between a and B is measured to be 12 cm. A bus and a truck meet each other after 6 hours. It is known that the speed ratio of the bus to the truck is 5:3. The actual distance between a and B is 12 * 4000000 = = 48 million cm = = 48
