The scale of a map is 1:5000000, which indicates that the distance on the map is ()
one
-----------
five million
1 cm on the diagram
It's actually 50 kilometers
On the map with a scale of 1:5000000, the distance between the two places is 6cm. After driving from the two places at the same time for three hours, the two cars meet. The speed ratio of car a to car B is 2:3. How many kilometers do car a and car B travel per hour?
The actual distance between the two places: 6 △ 15000000 = 30000000 (CM), 30000000 cm = 300 km, the speed of car a: 300 △ 3 × 22 + 3, = 100 × 25, = 40 (km); the speed of car B: 300 △ 3-40, = 100-40, = 60 (km); a: car a travels 40 km per hour, car B travels 60 km per hour
On a map with a scale of 1:7500000, it is measured that the distance between a and B is 10 cm. A bus and a truck are running from a and B at the same time,
When we meet in three hours, we know that the speed ratio of the bus to the truck is 3:2. How many kilometers does the truck travel per hour? How many hours does the bus travel before it reaches Jiadi
7500000 * 0.1/3 * 2 / 5 = 100000 M / h = 100 km / h
Three times two thirds means that the bus will arrive at Jiadi in another two hours
On a map with a scale of 1:6000000, it is measured that the distance between a and B is 10 cm. If a train leaves from a place to B at 8:00 a.m. at a speed of 120 km, when can it arrive in the afternoon? (decimal Report No. 1132)
10 △ 16000000 = 10 × 6000000 = 6000000 (CM), 6000000 cm = 600 km; 600 △ 120 = 5 (H), 8 + 5 = 13 (H) (i.e. 1 PM); a: arrive at 1 pm
