Question

Задача мотоциклист проехал в первый день 4 ч со скоростью 60 км/ч,во второй день-столько же времени со скоростью 55 км/ч. всего ему надо проехать 710 км. с какой скоростью он должен ехать дальше, чтобы преодолеть оставшееся расстояние за 5 часов.

Answer 1

1)4*60 = 240 км
2)4*55= 220 км проехал со ск.55 км/ч
3)240+220=460 км проехал
4)710-460=250 км осталось проехать
5) 250:5=50 км/ч с такой скоростью он должен проехать оставшийся путь

Answer 2

60*4=240
55*4=220
710-(240+220)=250
250/5=50 км/ч

Answer 3

Problem Analysis

To solve this problem, we need to find the speed at which the motorcyclist should travel in order to cover the remaining distance of 710 km in 5 hours. We are given that on the first day, the motorcyclist traveled for 4 hours at a speed of 60 km/h, and on the second day, the motorcyclist traveled for the same amount of time at a speed of 55 km/h.

Solution

To find the speed at which the motorcyclist should travel to cover the remaining distance in 5 hours, we can follow these steps:

1. Calculate the total distance covered on the first day: distance_day1 = time_day1 * speed_day1. 2. Calculate the total distance covered on the second day: distance_day2 = time_day2 * speed_day2. 3. Calculate the total distance covered in the first two days: total_distance = distance_day1 + distance_day2. 4. Calculate the remaining distance: remaining_distance = total_distance - 710 km. 5. Calculate the speed needed to cover the remaining distance in 5 hours: speed_remaining = remaining_distance / 5 hours.

Let's calculate the values step by step:

1. Calculate the total distance covered on the first day: - time_day1 = 4 hours - speed_day1 = 60 km/h - distance_day1 = 4 hours * 60 km/h = 240 km.

2. Calculate the total distance covered on the second day: - time_day2 = 4 hours - speed_day2 = 55 km/h - distance_day2 = 4 hours * 55 km/h = 220 km.

3. Calculate the total distance covered in the first two days: - total_distance = distance_day1 + distance_day2 = 240 km + 220 km = 460 km.

4. Calculate the remaining distance: - remaining_distance = total_distance - 710 km = 460 km - 710 km = -250 km.

Since the remaining distance is negative, it means that the motorcyclist has already covered more than the total distance of 710 km in the first two days. Therefore, there is no need to calculate the speed needed to cover the remaining distance in 5 hours.

Conclusion

Based on the calculations, the motorcyclist has already covered more than the total distance of 710 km in the first two days. Therefore, there is no need to calculate the speed needed to cover the remaining distance in 5 hours.
