From two cities located at a distance of 840 km, two cars drove towards each other

From two cities located at a distance of 840 km, two cars drove towards each other and met after 6 hours. What was the speed of the second car if the first was moving at a speed of 75 km / h?

1. Let’s calculate the distance that a car traveled in 6 hours, the speed of which was 75 kilometers per hour.

75 * 6 = 450 kilometers.

2. Let’s find which way the second car has covered.

840 – 450 = 390 kilometers.

3. Find out the speed of another car if it is known that it covered 390 kilometers in 6 hours.

390/6 = 65 kilometers.

Answer: The speed of the second car was 65 kilometers per hour.
