Question

Із Києва у Харків виїхав автобус і рухався без зупинок iз середньою швидкістю 45 км/год. Одночасно із Харко ва у Київ виїхав мотоцикліст і рухався без зупинок із середньою швидкістю 55 км/год. Через 4 год 50 хв вони зустрілися.визначіть відстань між ними.

Answer 1

Ответ:

V=45+55=100 км/год

t=4год 50хв=4 5/6 год

S=Vt

S=100×4 5/6=100×29/6= 483 1/3 км

Answer 2

To determine the distance between the bus and the motorcyclist, we can use the formula:

Distance = Speed x Time

Let's calculate the distance using the given information:

- The bus traveled from Kyiv to Kharkiv at an average speed of 45 km/h. - The motorcyclist traveled from Kharkiv to Kyiv at an average speed of 55 km/h. - They met after 4 hours and 50 minutes.

First, let's convert the time to hours. 4 hours and 50 minutes is equal to 4.83 hours.

Now, we can calculate the distance traveled by the bus and the motorcyclist:

- Distance traveled by the bus = 45 km/h x 4.83 hours = 217.35 km - Distance traveled by the motorcyclist = 55 km/h x 4.83 hours = 265.65 km

Therefore, the distance between them is the sum of the distances traveled by each:

- Distance between the bus and the motorcyclist = 217.35 km + 265.65 km = 483 km.

So, the distance between the bus and the motorcyclist is 483 kilometers.
