The fast and slow trains run from a and B at the same time and meet at a distance of 4km from the destination. The speed of the slow train is five sixth of that of the fast train. How many kilometers are there between the two places?

The fast and slow trains run from a and B at the same time and meet at a distance of 4km from the destination. The speed of the slow train is five sixth of that of the fast train. How many kilometers are there between the two places?


midpoint
4 × 2 ÷ (1-5 / 6) = 48 km
48 × 5 / 6 + 48 = 88 km
A: the distance between the two places is 88 kilometers



A and B vehicles leave from a and B at the same time and meet at a distance of 50 kilometers from the terminal. It is known that the speed ratio of a and B is 5; 3. How many kilometers are a and B away from each other?


A walks 50 × 2 more than B = 100 (km)
100 ÷ (5-3) = 50 (km)
50 × (5 + 3) = 400 (km)



A and B leave from a and B and meet at a distance of 30 km from the destination. It is known that a's speed is the same as B's
A and B leave from a and B and meet at a distance of 30 km from the destination. It is known that a's speed is 1.5 times of B's. how many kilometers are there between a and B?


A and B leave from a and B and meet at a distance of 30km [midpoint]. It is known that the speed of a is 1.5 times that of B. how many kilometers are there between a and B? 30 × 2 ^ (1.5-1) = 120 (km) 120 × 1.5 = 180 (km) 120 + 180 = 300 (km). A and B are 300km apart (*^__ ...



A and B leave from station AB at the same time. For the first time, they meet at 90km away from station A. after meeting, they continue to drive at the same speed and return to each other's place of departure immediately. For the second time, they meet at 50km away from station a to find the distance between two places


(90 × 3 + 50) △ 2, = 320 △ 2, = 160 (km). A: the distance between AB and ab is 160 km
