Question

Велосипедист и мотоциклист выехали одновременно из одного пункта В одном направлении скорость мотоциклиста 40 километров в час а велосипедист 11 км час Какое расстояние будет между ними через 3 часа какое расстояние было бы между ними что я за то же время если бы первоначальное расстояние составляло 5 км и мотоциклист догонял велосипедиста.

Answer 1

40*3=120 км проедет мотоциклист
11*3=33 км проедет велосепедист
120-33=87 км расст между ними будет
87-5=82 км будет между ними при усл , что 5 км

Answer 2

Calculation of Distance between the Cyclist and the Motorcyclist

To calculate the distance between the cyclist and the motorcyclist, we need to determine the distance each of them covers in 3 hours.

Given: - Speed of the motorcyclist = 40 km/h - Speed of the cyclist = 11 km/h

To find the distance covered by each of them, we can use the formula:

Distance = Speed × Time

For the motorcyclist: Distance covered by the motorcyclist = 40 km/h × 3 hours = 120 km

For the cyclist: Distance covered by the cyclist = 11 km/h × 3 hours = 33 km

Therefore, after 3 hours, the distance between the cyclist and the motorcyclist will be 120 km - 33 km = 87 km.

Calculation of Initial Distance between the Cyclist and the Motorcyclist

Now, let's calculate the initial distance between the cyclist and the motorcyclist if the motorcyclist catches up to the cyclist.

Given: - Initial distance between them = 5 km - Speed of the motorcyclist = 40 km/h - Speed of the cyclist = 11 km/h

To find the time it takes for the motorcyclist to catch up to the cyclist, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the difference between the speeds of the motorcyclist and the cyclist.

Relative speed = 40 km/h - 11 km/h = 29 km/h

Time taken for the motorcyclist to catch up = 5 km / 29 km/h = 0.1724 hours (approximately)

Now, let's calculate the distance between them at that time:

Distance covered by the motorcyclist = 40 km/h × 0.1724 hours = 6.896 km (approximately)

Therefore, if the initial distance between the cyclist and the motorcyclist is 5 km, the motorcyclist would catch up to the cyclist at a distance of approximately 6.896 km.

Please note that these calculations are based on the given speeds and times, and assume constant speeds throughout the duration.
