Question

Сергей и Михаил выехали на своих машинах из одного гаража в одно и то же время и разъехались в противоположные стороны. Сергей ехал со скоростью 87 км/ч, Михаил — 69 км/ч. Найди расстояние между машинами через 3 часа. ​

Answer 1

Ответ: 54

Пошаговое объяснение:

1) 87*3=261 - Проехал Сергей за 3 часа

2) 69*3=207- Проехал Михаил за 3 часа

3) 261-207=54 - Расстояние между машинами

Answer 2

Calculating the Distance Between Sergey and Mikhail's Cars

To find the distance between Sergey and Mikhail's cars after 3 hours, we can use the formula:

Distance = Speed × Time

Sergey's speed = 87 km/h Mikhail's speed = 69 km/h Time = 3 hours

Using the given speeds and time, we can calculate the distances traveled by both Sergey and Mikhail.

Calculations

Sergey's distance = 87 km/h × 3 h = 261 km Mikhail's distance = 69 km/h × 3 h = 207 km

Finding the Distance Between the Cars

To find the distance between the two cars, we can subtract Mikhail's distance from Sergey's distance.

Distance between the cars = Sergey's distance - Mikhail's distance Distance between the cars = 261 km - 207 km = 54 km

So, the distance between Sergey and Mikhail's cars after 3 hours is 54 km.
