Answer 3

A) Cost of a Bun

To find the cost of the bun, we can use the given information that Natasha paid 15 rubles for 3 cups of tea and that a bun costs 4 times more than one cup of tea.

Let's denote the cost of one cup of tea as x and the cost of the bun as y.

Given: - 3 cups of tea cost 15 rubles, so 3x = 15 - The bun costs 4 times more than one cup of tea, so y = 4x

We can solve for the cost of the bun using the given information.

B) Speed of the Cyclist

To find the speed of the cyclist, we can use the given information that a pedestrian walked 15 km in 3 hours and the cyclist's speed is 4 times greater.

Let's denote the pedestrian's speed as x km/h and the cyclist's speed as y km/h.

Given: - The pedestrian walked 15 km in 3 hours, so x = 15/3 - The cyclist's speed is 4 times greater than the pedestrian's speed, so y = 4x

We can solve for the speed of the cyclist using the given information.

C) Weight of Fruits in the Box

To find the weight of fruits in the box, we can use the given information that 3 boxes contain a total of 15 kg of fruits and that the box contains 4 times more fruits than a single box.

Let's denote the weight of fruits in a single box as x kg and the weight of fruits in the box as y kg.

Given: - 3 boxes contain a total of 15 kg of fruits, so 3x = 15 - The box contains 4 times more fruits than a single box, so y = 4x

We can solve for the weight of fruits in the box using the given information.
