Question

Расстояние между городами A и B вдвое меньше расстояния между B и C. Автомобиль, двигаясь со скоростью 50 км/ч, преодолел путь из A в C за 6 ч. Найдите расстояние от A до B

Answer 1

AC=50*6=300км
AB=300/2=150км

Answer 2

I can answer your question in detail. The distance between cities A and B is twice as small as the distance between B and C. A car, moving at a speed of 50 km/h, covered the distance from A to C in 6 hours. Find the distance from A to B.

Let x be the distance from A to B, and y be the distance from B to C. Then, we have the following equations:

x + y = 50 * 6 = 300 (1) - the total distance is equal to the speed multiplied by the time x = y / 2 (2) - the distance from A to B is half of the distance from B to C

Substituting (2) into (1), we get:

y / 2 + y = 300 y = 300 * 2 / 3 = 200

Therefore, x = y / 2 = 200 / 2 = 100

The distance from A to B is 100 km.
