the russian ice breaker Yamal can move forward through  2.3 meter 2.3 meter thick ice at a speed  5.5 kilometers
morpeh [17]

Answer:

Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.

Step-by-step explanation:

Given:

Speed  = 5.5 km/hr

Distance = 82 km

Let time be represented as 'x'.

We need to find the number of hours required to travel 82 km.

We know that Distance can be calculated by the product of Speed and time.

Framing above sentence in equation form we get;

Distance = Speed × Time

Substituting the given value we get;

82 = 5.5x

Hence The expression for number of hours is 82 = 5.5x

Solving the equation to find the value of x we get;

82 = 5.5x\\\\x=\frac{82}{5.5} = 14.90 \approx 15\ hrs

Hence Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.

3.49b + 4.39m = $140.04

Step-by-step explanation:

A B

Bread $3.19 $3.49

Milk $4.59 $4.39

Sue paid $137.24 in supermarket A

Sue paid $140.04 in supermarket B

Let

Price of bread A=$3.19

Price of bread B=$3.49

Price of milk A=$4.59

Price of milk B=$4.39

Quantity of Bread=b

Quantity of Milk=m

Pb=price of bread

Pm=price of milk

Qb=Quantity of bread

Qm=Quantity of milk

For each supermarket

Supermarket A Equation

PbQb + PmQm =$137.24

3.19b+ 4.59m = 137.24

Supermarket B Equation

PbQb + PmQm=$140.04

3.49b + 4.39m = $140.04

Combining both equations

3.19b + 4.59m = 137.24

3.49b + 4.39m = $140.04
