Question

После того, как велосипедист проехал 3/10 части от расстояния между двумя городами, до половины пути ему оставалось проехать еще 18 км. Найдите расстояние между двумя городами ПЖЖЖ помогите​

Answer 1

3/10x+18=1/2x

18=1/2x-3/10x

18=2/10x

x=18÷2/10=18•10/2

x=90

Answer 2

Calculating the Distance Between Two Cities

To find the distance between the two cities, we can use the information provided about the cyclist's journey.

Let's denote the total distance between the two cities as D.

The cyclist has traveled 3/10 of the distance, which is 3/10 * D, and has 7/10 of the distance remaining, which is 7/10 * D.

According to the given information, 7/10 * D = 18 km.

Calculating the Distance

To find the total distance D, we can use the given information to solve for D.

7/10 * D = 18 km

To find D, we can multiply both sides of the equation by 10/7:

D = 18 km * (10/7)

Solving for D

Let's calculate the value of D:

D = 18 km * (10/7) = 25.71 km

So, the distance between the two cities is 25.71 kilometers.
