Question

СРОЧНО СРОЧНОМотоциклист должен был проехать расстояние 120 км между двумя городами за 4 часа.Он остановился спустя 2 часа и отдыхал 0.5 часов.С какой скоростью нужно ехать мотоциклисту чтобы вовремя добраться до второго города. СРОЧНО ПЛИИИИИИИИИЗ

Answer 1

1)120:4=30 км/ч должен был ехать с этой скоростью
2) 2*30 + 1,5х=120
3)1,5х=120-60
4)1,5х=60
5)х=40
Ответ : со скоростью 40 км/ч

Answer 2

Calculation of Motorcycle Speed

To calculate the speed at which the motorcyclist needs to travel to reach the second city on time, we can use the formula:

Speed = Distance / Time

Given: - Distance between the two cities: 120 km - Total time available: 4 hours - Rest time: 0.5 hours

To calculate the travel time, we subtract the rest time from the total time:

Travel time = Total time - Rest time

Travel time = 4 hours - 0.5 hours = 3.5 hours

Now, we can calculate the speed:

Speed = Distance / Travel time

Speed = 120 km / 3.5 hours

Using a calculator, we find that the motorcyclist needs to travel at a speed of approximately 34.29 km/h to reach the second city on time.

Please note that this calculation assumes a constant speed throughout the journey and does not take into account factors such as traffic or road conditions.
