A bus with a speed of 85 km / h and a car with a speed of 70 km / h drove from one city to another at the same time in one direction. When the bus was in place, the car remained 30 km. Find the distance between cities.

1) Let x be the time during which the bus and the car were traveling.

2) Find the distance the bus traveled:

85 * x.

3) Find the distance the car has traveled:

70 * x.

4) Let’s compose and solve the equation:

85 * x – 70 * x = 30;

15 * x = 30;

x = 30/15;

x = 2.

5) Find the distance to the city:

85 * 2 = 170 km.

Answer: The distance to the city is 170 km.
