Answer 1

1) 5 часов 
2) 6x8=48
3) 140x7=980 rp

Answer 2

а)1*5=5(часов)-будут идти туристы

б)6*8=48(м/кв)-пложадь всей квартиры

в)140 *7=980грамм-крупы вмещает в себя банка

Answer 3

Task A: Time Taken to Complete the Journey

If the tourists have covered 1/5 of the total distance in 1 hour, we can calculate the total time required to complete the entire journey at the same speed.

Let's denote the total time required as T and the total distance as D.

Using the given information: - Distance covered in 1 hour = 1/5 of the total distance - Time taken = 1 hour

We can use the formula: Speed = Distance / Time to find the speed at which the tourists are traveling.

Then, we can use the speed to calculate the total time required to complete the journey.

Calculation:

- Speed = Distance / Time - Speed = (1/5)D / 1 - Speed = D / 5

Now, to find the total time required to complete the journey: - Total Time (T) = Total Distance (D) / Speed - T = D / (D / 5) - T = 5 hours

So, the tourists will take 5 hours to complete the entire journey if they continue at the same speed.

Task B: Finding the Total Area of the Apartment

Given that the kitchen's area is 6 square meters, which is 1/8 of the total area of the apartment, we can calculate the total area of the apartment.

Let's denote the total area of the apartment as A.

Using the given information: - Kitchen's area = 6 square meters - Kitchen's area is 1/8 of the total area of the apartment

We can set up the equation: Kitchen's area = (1/8) * Total area of the apartment

Calculation:

- 6 = (1/8)A - A = 6 * 8 - A = 48

So, the total area of the apartment is 48 square meters.

Task C: Capacity of the Jar

If 140 grams of cereal fills 1/7 of the jar's capacity, we can calculate the total capacity of the jar.

Let's denote the total capacity of the jar as C.

Using the given information: - Cereal filled = 140 grams - Cereal filled is 1/7 of the jar's capacity

We can set up the equation: 140 grams = (1/7) * Total capacity of the jar

Calculation:

- 140 = (1/7)C - C = 140 * 7 - C = 980

So, the jar can hold 980 grams of the cereal.
