Simultaneously, two cars drove towards each other from two cities, the distance between which was 462 km. One was traveling at a speed of 86 km / h, and the other was at 68 km / h. What is the distance between them in 2 hours?

1) How many kilometers will the first car travel in 2 hours? To find the distance, you need to multiply the speed by time.

86 * 2 = 172 (km).

2) How many kilometers will the second car travel in two hours?

68 * 2 = 136 (km).

3) How many kilometers will both cars travel in two hours?

172 + 136 = 308 (km).

4) What is the distance between cars in 2 hours?

462 – 308 = 154 (km).

Answer. 154 kilometers.

Differently:

1) Find the speed of convergence of cars. When moving towards each other, the speed of approach is equal to the sum of the speeds of moving objects.

86 + 68 = 154 (km / h).

2) How many kilometers will both cars travel in 2 hours?

154 * 2 = 308 (km).

3) What will be the distance between cars in 2 hours?

462 – 308 = 154 (km).

Answer. 154 kilometers.
