The two passenger and freight cars leave from both places at the same time and meet at 12 kilometers away from the midpoint. It is known that the ratio of passenger car travel to freight car travel is 3:2. How many kilometers is the distance between two places?
The total distance share: 3 + 2 = 5, the total distance of bus line: 3 △ 5 = 35, the distance between a and B: 12 △ 35-12, = 12 △ 110, = 120 km; a: the distance between a and B is 120 km
The two passenger and freight cars leave from both places at the same time and meet at 12km away from the midpoint. It is known that the ratio of the passenger car's journey to the freight car's journey at this time is
9: 8. How many kilometers are there between Party A and Party B? Tell us the reason for 12x2
12x2 means that passenger cars travel more than freight cars when they meet, which accounts for (9-8) / (9 + 8) = 1 / 17 of the whole journey
The whole journey is 12x2 △ 1 / 17 = 408km
The two passenger and freight cars leave from a and B at the same time. When they meet, the ratio of the journey of the passenger car to that of the freight car is 7:5. It is known that the passenger car travels 120 kilometers more than the freight car
How many kilometers are there between a and B?
Suppose the bus travels x kilometers when meeting, then the truck travels 5 / 7 X. solve the equation X-5 / 7X = 120, so x = 420, so the distance between a and B is 420 + 300 = 720 kilometers
