# At 8 o’clock in the morning, a bus left city A for city B at a speed of 56 km / h, and at 11 o’clock in the afternoon

**At 8 o’clock in the morning, a bus left city A for city B at a speed of 56 km / h, and at 11 o’clock in the afternoon, a truck left B for A at a speed of 32 km / h. At what time and at what distance from the city did they meet, if the distance between the cities is 520 km?**

1) How long was the bus until the truck started moving?

11 – 8 = 3 (h).

2) How many kilometers did the bus travel in 3 hours? To find the distance, you need to multiply the speed by time.

56 * 3 = 168 (km).

3) What was the distance between the bus and the truck when the truck started moving?

520 – 168 = 352 (km).

4) What is the speed of convergence between a truck and a bus? When moving towards each other, the speed of approach is equal to the sum of the speeds of the truck and the bus.

56 + 32 = 88 (km / h).

5) How long was the truck before meeting the bus?

352: 88 = 4 (h).

6) What time did the truck and bus meet?

11 + 4 = 15 (H).

7) At what distance from B did the truck and the bus meet? This distance is equal to the distance traveled by the truck.

32 * 4 = 128 (km).

Answer. The meeting took place at 15:00, 128 kilometers from V.
