Question

1 для туристического похода было приготовлено 7 коробок рыбных и 9 коробок мясных консервов с одинаковым количеством банок в каждой коробке. Мясных было приготовлено на 20 банок больше чем рыбных. Сколько приготовили мясных консервантов? Сколько рыбных? 2 Машина двигалась со скоростью 50 км/ч преодолела расстояние между двумя городами за три часа. За какое время велосипедист дввагаясь со скоростью 15 км/ч проедет половину этого расстояние?

Answer 1

1)9-7=2 20:2=10 банок в 1 коробке 7*10=70 банок рыбных 9*10=90 банок мясных консерв 2)50*3=150 км расстояние между двумя городами 150:2=75 км половина расстояния 75:15=3 часа велосипедист проедит половину расстояния

Answer 2

Question 1:

For a tourist hike, 7 boxes of fish cans and 9 boxes of meat cans were prepared, with the same number of cans in each box. There were 20 more cans of meat than fish. How many cans of meat and fish were prepared?

To solve this problem, let's assume the number of cans in each box is 'x'.

Given that there are 20 more cans of meat than fish, we can set up the following equation:

9x - 7x = 20

Simplifying the equation, we get:

2x = 20

Dividing both sides by 2, we find:

x = 10

Therefore, each box contains 10 cans.

To find the number of meat cans, we multiply the number of boxes (9) by the number of cans in each box (10):

9 * 10 = 90

So, 90 cans of meat were prepared.

To find the number of fish cans, we multiply the number of boxes (7) by the number of cans in each box (10):

7 * 10 = 70

So, 70 cans of fish were prepared.

Answer: - The number of meat cans prepared is 90. - The number of fish cans prepared is 70.

Question 2:

A car traveled at a speed of 50 km/h and covered the distance between two cities in three hours. How long will a cyclist take to cover half of this distance, traveling at a speed of 15 km/h?

To solve this problem, we can use the formula:

Time = Distance / Speed

Given that the car traveled at a speed of 50 km/h and covered the distance in three hours, we can calculate the distance using the formula:

Distance = Speed * Time

Distance = 50 km/h * 3 hours = 150 km

To find the time it will take for the cyclist to cover half of this distance, we divide the distance by 2 and divide it by the speed of the cyclist:

Time = (Distance / 2) / Speed

Time = (150 km / 2) / 15 km/h = 5 hours

Therefore, the cyclist will take 5 hours to cover half of the distance.

Answer: The cyclist will take 5 hours to cover half of the distance.
