A coat in London costs £60. The same coat in Dublin costs €105.60. The exchange rate is £1 = €1.65. In which city is the coat ch
Pie

Answer:

The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin

Step-by-step explanation:

Given

Cost of coat in London = £60

Cost of coat in Dublin = €105.60

In order to find where the coat is cheaper, the price should be in same unit

It is also given that

£1 = €1.65

so,

Price of coat in Euro will be:

P = 60 * 1.65 = 99

So the price of coat in London is 99 Euros

Comparing both the prices we see that

Price in London < Price in Dublin

99 < 105.60

The difference in price is:

=105.60-99= 6.6\ Euros

Hence,

The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin

The Russian ice breaker you mall can move forward through 2.3 m thick ice at a speed of 5.5 km/h. Right and solve a multiplicati
viktelen [127]

Answer:

The Multiplication equation to find the number of hours taken to travel the distance is 5.5\times x=82.5.

It will taken <u>15 hours</u> by  Russian ice breaker to travel a distance of 82.5 km through the ice.

Step-by-step explanation:

Given:

Thickness of the ice = 2.3 m

Speed while moving forward = 5.5 km/h

Distance to travel through the ice = 82.5 km

We need to write and solve the multiplication equation to find the number of hours taken to travel the distance.

Solution:

Let the number of hours taken to travel the distance be 'x'.

Now We know that;

By Distance formula;

Distance traveled is equal to Speed while moving forward multiplied by the number of hours taken to travel the distance.

framing in equation form we get;

5.5\times x=82.5

Hence The Multiplication equation to find the number of hours taken to travel the distance is 5.5\times x=82.5

On Solving above equation we get;

Dividing both side by 5.5 we get;

\frac{5.5x}{5.5}=\frac{82.5}{5.5}\\\\x=15 \ hrs

Hence It will taken <u>15 hours</u> by  Russian ice breaker to travel a distance of 82.5 km through the ice.
