On a map with a scale of 1:5000000, the distance between the two places is 6cm. Two cars a and B drive from the two places at the same time and meet each other two hours later. It is known that the speed ratio of car a to car B is 2:3. How many kilometers does car a travel per hour?
Hanying warm for you
6 cm △ 1 / 5 000
=30 000 000 cm
=300 km
300 △ 2 = 150 km
Speed of car a: 150 × 2 / (2 + 3) = 60 km
Speed of vehicle B: 150 × 3 / (2 + 3) = 90 km

If you don't understand,
Until the completion of understand this problem!
The first time they met 75 kilometers away from a, the two cars continued to move forward and returned immediately after reaching their destination. The second time they met 33 kilometers away from B, how many meters away is ab?
The first time a walked 75 kilometers
The second time a walked 75x3 = 225km
The distance between the two places is 225-33 = 192 km
A and B depart from a and B at the same time. For the first time, they meet 75 km away from A. after meeting, they continue to move forward and return to their destination. For the second time, they meet 55 km away from B. A and B are far away from each other______ Kilometers
75 × 3 = 225 (km), 225-55 = 170 (km)
A truck and a motorcycle leave AB at the same time, and the two vehicles meet for the first time at a distance of 60 km from a place on the way A math problem, no equations
If the truck runs 60 km in the first encounter, the truck should travel 60 × 2 = 120 km in the second encounter
Then: 120-30 × 2 = 60 km, which is the distance between the first meeting point and the second meeting point
Total length: 60 + 60 + 30 = 150 km
