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. Sum of digits of a two digit number is 14. When 18 is added to the original number, then the new number is obtained by exchan
Nitella [24]

Answer:

let the numbers be xy

general form of the number =10x+y

sum of digits of a number =14

x+y=14………[1]

if 18 is added to the number, then digits are interchanged

10x+y+18=10y +x

9x-9y=-18

X-y=-2………[2]

the linear equations are 1) x+y=14

2) X-y=-2

adding [1],[2]

2x=12

x=6

x+y=14

y=14-x

y=14-6

y=8

there fore the number =10*6+8

=68

check:-

1)6+8=14

2)68+18=86

I hope this helped!
