Question

Мотоциклист ехал в первый день 4 часа со скоростью 60 км/ч, во второй день - столько де времини со скоростью 55км/ч.Всего ему надо проехать 710 км. С какой скоростью он должен ехать дальше,чтобы преодолеть оставшееся растояние за 5 ч?

Answer 1

1)4*60=240(км)-за 4 часа в первый день

2)4*55=220(км)-за 4 часа во второй день

3)240+220=460(км)-за два дня проехал

4)710-460=250(км)-осталось ехать

5)250:5=50(км/ч)-должен ехать в третий день

Ответ: со скоростью 50 км/ч должен проехать оставшееся расстояние. 

Answer 2

Problem Analysis

A motorcyclist traveled for 4 hours on the first day at a speed of 60 km/h and for an unknown amount of time on the second day at a speed of 55 km/h. The total distance the motorcyclist needs to travel is 710 km. The question is: at what speed should the motorcyclist continue traveling in order to cover the remaining distance in 5 hours?

Calculation

To find the speed at which the motorcyclist should continue traveling, we need to calculate the distance covered on the first day and the distance covered on the second day. Then, we subtract the total distance covered from the remaining distance and divide it by the remaining time to find the required speed.

Let's calculate the distances covered on the first and second days:

- Distance covered on the first day: 4 hours * 60 km/h = 240 km - Distance covered on the second day: (total distance - distance covered on the first day) = 710 km - 240 km = 470 km

Now, we can calculate the required speed to cover the remaining distance in 5 hours:

- Required speed = (remaining distance) / (remaining time) = 470 km / 5 hours = 94 km/h

Therefore, the motorcyclist should continue traveling at a speed of 94 km/h to cover the remaining distance in 5 hours.

Answer

The motorcyclist should continue traveling at a speed of 94 km/h in order to cover the remaining distance of 470 km in 5 hours.
