Question

Answer 1

Answer:

1 liter /km

Step-by-step explanation:

According to the information provided in the question it is given as

Peter drove a total of 100 km and used 100litres of petrol.

We need to  calculate the rate at which the petrol was used in kilometers per liter

100 km = 100 liter

1km = x liter

This is because we need to find the km / liter

A proportion is a statement that two ratios are equal. ... In a proportion, the product of the means equals the product of the extremes.

$100=100\\1 =x$

$100x=100\\x=\frac{100}{100} \\x= 1 liter$

Hence the rate at which the petrol was used in km /liter is 1liter/ km
