The Petroleum Algorithm
This is for all you math geeks out there.
I car share with two other people and we're trying to work out how much each person should pay for petrol. We all go to work in the same car and I drive.
Heres the scenario: Theres three of us in a car (A, B & C). The total cost of petrol for 5 days is £30.
Assume A travelled for all 5 days, how much should he pay?
B travelled with them for 4 days, how much should he pay?
And C only travelled with them for 2 days, how much should he pay?
_______________________________________________________
Heres what ive worked out so far.
weeks petrol = £30 (5 days)
divided by the three of us= £10 per person (5 days)
I drove B for four days, therefore £10/5 to figour out how much per day = £2
They had such great voices - Loveeee it!
