Laura, I looked it up on the website. You are quite right it is not all speed/time/distance.
•find average speeds
•deal with multiple variables including wind-speed, cargo weight and fuel usage
•find journey times
•cross-reference tables of data
•analyse maps
•extract crucial information from wordy questions
•determine fuel consumption
•give ETAs
You don't need a tutor, you just need to create the sums yourself. You are in a car, it is doing 60 mph. You have 12 miles to go. How long will it take? Your car does 30 mpg, how much fuel will it use? What is that in gallons per hour?
Note the units I used. It is not all metric. How many kilos in a lb? Metres in a nautical mile etc.
Do look at the OASC sticky, you will find more there.
