The distance between the two places is 200 km. The speed of vehicle a is 70 km / h, and that of vehicle B is 50 km / h. both vehicles run in the same direction at the same time How long do we meet?
751321261 ,
200 (70-50) = 10 (hours)
A and B start from a and B at the same time and travel in opposite directions. A travels 60 kilometers per hour and B 75 kilometers per hour. The two vehicles meet at 45 kilometers from the midpoint. How many kilometers are there between a and B?

Encounter time: 45 × 2 △ 75-60 = 6 hours
Distance: (75 + 60) × 6 =?
It's better to think independently
A and B from a to B, B car 30 kilometers per hour, a car 45 kilometers per hour, B car starts 2 hours before a car starts, two cars arrive at B at the same time. Find the distance between a and B. (hint: the time required for the fast train to catch up with the slow train is x better.)
45 × [30 × 2 ^ (45-30)], = 45 × [60 ^ 15], = 45 × 4, = 180 (km); answer: the distance between AB and ab is 180 km
