From two cities, the distance between which is 1020 km, two cars simultaneously left towards each other.

From two cities, the distance between which is 1020 km, two cars simultaneously left towards each other. The speed of the first car is 75 km / h and the speed of the second is 12 km / h less than the speed of the first. At what distance. Cars will be separated from each other in 4 hours.

Let’s solve the task of actions with explanations. 1) 75 – 12 = 63 kilometers per hour – h speed of the second car; 2) 75 * 4 = 300 kilometers – the distance covered by the first car in 4 hours at a speed of 75 kilometers per hour; 3) 63 * 4 = 252 kilometers – the distance covered by the second car in 4 hours at a speed of 63 kilometers per hour; 4) 300 + 252 = 552 kilometers – the distance that two cars traveled together; 5) 1,020 – 552 = 468 kilometers – the distance at which two cars were in 4 hours. Answer: 468 kilometers.
