The two cars left the two places at the same time. Car a met car B after 164 kilometers. At this time, car a was 15 kilometers away from the midpoint of the two places, It is known that car B travels 48.5 kilometers per hour. How many kilometers did car B travel when they met? Use the equations

The two cars left the two places at the same time. Car a met car B after 164 kilometers. At this time, car a was 15 kilometers away from the midpoint of the two places, It is known that car B travels 48.5 kilometers per hour. How many kilometers did car B travel when they met? Use the equations

Set up B car line x kilometers
X-15=164+15
X=164+15+15
X=194

A and B vehicles run from AB to ab at the same time. After 5 / 8 hours, they meet at a distance of 10 km from the midpoint. It is known that a vehicle runs 9 / 20 of the whole journey, and the speed of a is faster
Degree is () km per hour. If we meet and keep going, B will arrive at point a in () hours

B: 1-9 / 20 = 11 / 20 B: 10 × 2 = 20 (km) B: 11 / 20-9 / 20 = 1 / 10 A: 200 × 9 / 20 = 90 (km) a: 90 △ 5 / 8 = 144 (km / h) B: 200-90 △ 5 / 8 = 1

Party A and Party B travel from ab at the same time. After 2 / 3 hours, they meet at the place 9km away from the midpoint. It is known that Party A has traveled 13 / 20 of the whole journey. Could you tell me about AB
Is it () km away?

9÷（13/20-1/2）
=9÷3/20
=60 km

The speed ratio of the fast and slow cars is 5:3. The two cars run from two places at the same time, and they meet at 120 km away from the midpoint. How many kilometers does the slow car travel at this time?

The distance of the whole journey: 120 △ 12-35 + 3 = 120 △ 18 = 960 (km) the kilometers of the car: 960 × 35 + 3 = 360 (km) a: at this time, the slow car runs 360 km
