The speed of train a is six seventh of that of train B At the same time, the two trains leave from station a and station B 364km apart. After 4:00, they meet on the way. The speed of car a is six seventh of that of car B. the speed of car a is six seventh of that of car B. what are the speeds of car a and station B? Hurry up, hurry up, the slowest is tonight
The two trains leave from station a and station B 364km apart at the same time, and meet on the way after 4 o'clock. The speed of train a is 6 / 7 of that of train B. what are the speeds of train a and train B respectively?
The speed of car B is:
364÷4÷（1+6/7）
=91÷13/7
=49 km / h
The speed of car a is:
49 × 6 / 7 = 42 km / h
It is known that the speed of the passenger and freight cars is 5:4, and how many km per hour the passenger and freight cars travel
The passenger and freight cars leave 315km away from each other at the same time and meet in 7 / 2 hours. Given that the speed ratio of the passenger and freight cars is 5:4, how many km does the passenger and freight cars travel per hour?
Speed sum = distance △ time = 315 △ 7 / 2 = 90
Bus speed = 90 × 5 / 9 = 50
Truck speed = 90 × 4 / 9 = 40
The distance between two places is 315km. The two cars run from two places at the same time and meet each other in 7 / 2 hours. The speed ratio of the two cars is 4:5
480*（7-5）/（7+5）
=480*2/12
=80 km
