On the map of scale 1:3000000, the distance between the two places is 6cm. Two cars a and B drive from the two places at the same time and meet at 4 hours It is known that the speed ratio of car a and car B is 4:5. How many kilometers per hour does car a and car B travel? I want answers and reasons, reasons for doing so. Solutions. Please list them one by one
The actual distance between the two places: 3000000 × 6 = 18000000 (CM) = 180km (1cm in the figure = 3000000cm in reality) the two vehicles travel in total per hour: 180 △ 4 = 45 (km) (speed and = distance △ time) the speed of each vehicle is 45 △ 4 + 5 = 5 (km) (the speed of the two vehicles in total
1. On the map with the scale of 1:3000000, the distance between a and B is 50cm
The two places leave each other and meet each other in 10 hours. Bus a travels 76 kilometers per hour, but how many kilometers per hour does bus B travel?
Actual distance = 50 * 300000 = 150000000cm = 1500km
B vehicle speed = 1500 / 10-76 = 74 km / h
