Question

Гонщики проехали за два дня 540 км. В первый день они ехали 3 часа со скоростью 100км/ч, во второй день они ехали со скоростью 120 км/ч. Сколько часов были гонщики в пути во второй день?

Answer 1

Ответ:

Пошаговое объяснение:

1) 100*3=300 (км) - расстояние, которое гонщики проехали в первый день

2) 540-300= 240 (км) - расстояние, которое гонщики проехали во второй день

3) 240:120= 2 (часа) - были гонщики в пути во второй день

Answer 2

Calculation of the Total Time Spent by the Racers on the Second Day

To calculate the total time spent by the racers on the second day, we need to determine the distance they covered and divide it by their speed.

Given information: - Total distance covered in two days: 540 km - Speed on the first day: 100 km/h for 3 hours - Speed on the second day: 120 km/h

Let's calculate the distance covered on the first day: - Speed on the first day: 100 km/h - Time on the first day: 3 hours - Distance covered on the first day: 100 km/h * 3 hours = 300 km

To find the distance covered on the second day, we subtract the distance covered on the first day from the total distance: - Distance covered on the second day: 540 km - 300 km = 240 km

Now, we can calculate the time spent on the second day: - Speed on the second day: 120 km/h - Distance covered on the second day: 240 km - Time spent on the second day: Distance / Speed = 240 km / 120 km/h = 2 hours

Therefore, the racers were in transit for 2 hours on the second day.
