Acar wash uses gas at the rate of 1 litre for every 6.5 kilometres. determine the number of litres used if it travels x kilometres

The number of liters used by the car on travelling kilometers can be given as : liter.

Step-by-step explanation:

Given:

A car wash uses gas at the rate of 6.5 kilometers per liter.

To determine the number of liters used if it travels kilometers.

Solution:

We will use unitary method to determine the number of liters of gas used by the car if it travels kilometers.

If 6.5 kilometer consumes 1 liters of gas.

So, 1 kilometer will consume = liters

Thus, for kilometers will consume = liters

Thus, number of liters used by the car on travelling kilometers can be given as : liter.

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
