Question

Из Москвы в дачный поселок выехала грузовая машина со скоростью 43км/ч, В тоже время из этого поселка в Москву выехала легковая машина со скоростью 56км/ч. Расстояние между Москвой и дачным поселком 198 км. Через сколько часов машины встретятся?

Answer 1

1) 43+56=99 (км/ч) - общая скорость
2) 198/99=2 (ч)
Ответ: через 2 часа

Answer 2

Calculation of Meeting Time

To calculate the time it takes for the two vehicles to meet, we can use the formula:

Time = Distance / Relative Speed

Given that the distance between Moscow and the dacha village is 198 km, and the truck is traveling at a speed of 43 km/h while the car is traveling at a speed of 56 km/h, we can calculate the time it takes for them to meet.

The relative speed of the two vehicles is the sum of their individual speeds:

Relative Speed = Speed of Truck + Speed of Car

Relative Speed = 43 km/h + 56 km/h = 99 km/h

Now, we can calculate the time it takes for the two vehicles to meet:

Time = Distance / Relative Speed

Time = 198 km / 99 km/h = 2 hours

Therefore, the truck and the car will meet after 2 hours.

Please note that the above calculation assumes that the two vehicles are traveling towards each other in a straight line without any stops or delays along the way.
