mens with 30 litres of petrol it would go=150/25*30

==>180 km.

in this method we first found the value for one unit or the unit rate this is done by the comparison of two different properties for example when you compare total cost to number of items we get cost per item if you take distance travelled to time taken we get a distance per unit time you can see that we often use per to mean for each.

for example kilometre per hour children per teacher etc Denot unit rates.
