Please help / The Hotel is 163 miles from your house. your car travels 10.5 miles for every litre of petrol. Work out approximately how many litres of petrol the journey will use.

2/The price of petrol is 138.9 pence per litre Work out the approximate cost for the petrol to the hotel .

3/ you expect to travel 50 miles in each hour of a jurney how long the whole journey should take

The answers are:

Step-by-step explanation:

Given:

Distance of Hotel and car = 163 miles

Distance travelled by car per liter = 10.5 miles

The number of liters will be obtained by dividing the total distance by distance travelled in one liter.

So,

2. Cost for petrol:

Cost of petrol per liter = 138.9 pence per liter

Then the total cost of petrol will be:

3. Time taken for journey

Distance travelled in an hour = speed = 50 miles per hour.

The speed is given by the formula:

Putting the values

It will take: 3 hours and 0.26*60 = 15.6 minutes => 3 hours 16 minutes

Hence,

The answers are:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
