While in europe, if you drive 111 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 42.0 mi/gal

First put everything into the same measurements.
111 km = 111km
42mpg = 67.592kpg
1 U.K. Gallon = 4.546 liters
67.592/4.546 = 14.8684557853
42mpg = 14.87kpl (kilometers per liter)
1.10 euros/liter = 1.10 euros/liter

If you drive 111 km a day and go 14.87 km a liter, divide 111 by 14.87 to get about 7.46, which is how many liters you will use a day. Multiply the price, 1.10 euros, by the number of liters, 7.46, to get the daily price of gas, which is about 8.206 a day. Multiply by 7 (num of days in week) to get about 57.44

It cost about 57.44 euros for one week of gas.

I hope I'm not too late! And hopefully that is right! No guarantees lol

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
