Расстояние между городами а и б равно 180 км это расстояние легковая машина проедет за 2 часа а грузовая за 3 часа. из а в б выехал грузовик,одновременно с ним выехала легковая машина.на каком расстоянии от города а встретятся машины

Answer 1

1) 180:2=90 (км) легковая машина
2) 180:3=60 (км) груз.машина
3) 90+60=150 (км) всего
ответ:150 км. всего

Answer 2

Calculation of Meeting Point

To determine the distance at which the two vehicles will meet, we can use the concept of relative speed. The relative speed of the two vehicles is the sum of their individual speeds.

Given that the car travels 180 km in 2 hours and the truck travels the same distance in 3 hours, we can calculate their respective speeds:

- Speed of the car: 180 km / 2 hours = 90 km/h - Speed of the truck: 180 km / 3 hours = 60 km/h

The relative speed of the two vehicles is the sum of their speeds: 90 km/h + 60 km/h = 150 km/h.

To find the meeting point, we can use the formula:

Meeting Point = (Speed of Car / Relative Speed) * Total Distance

Substituting the values, we get:

Meeting Point = (90 km/h / 150 km/h) * 180 km = 108 km

Therefore, the two vehicles will meet at a distance of 108 km from city A.
