In a few hours, the car must travel 900 km. 10 hours after the start of the movement, he had to drive another 100 km. How many hours will the car cover the remaining distance if the speed does not change?

2) 800: 10 = 80 (km / h) – vehicle speed
3) 100: 80 = 1.25 (h) – the time during which the car covered the remaining 100 km
Answer: in 1.25 hours the car has covered 100 km
