Keep the Ship Afloat: First Mate Maths.

This is your Captain speaking, as the ‘First Mate’ of this boat it is your main job to keep us afloat. Keep an eye on the computer display and answer any questions I have. Good luck and don’t fall asleep.

OK ‘First Mate’ your first job is to look at the fuel gauges , unfortunately the system has glitched, can you work out how much fuel is in each tank?
The slop and sewer gauges also need looking at.
What is the consumption of fuel per hour?
How many litres (l) of fuel is used in 2 hours?
I will take us 5 hours to get to our destination, we have 393 litres of fuel, I think that is enough to get us to our destination, am I right or wrong? Explain why.

What other information can you get from this display?

OK, ‘First Mate’ Can you please show this time on an analogue clock.
It takes us 5 hours to get to our destination, what time will we arrive?
:
We left port at 6:30 how long have we been sailing for?

A great first day on the job ‘First Mate’ but we need to keep our wits about us today as anything can happen at sea

OK ‘First Mate’ our fuel display has been upgraded but it is still having problems showing how many litres are in each tank, can you fill these in please.
What is the difference in amounts of fuel between the two tanks?
If we use 500 litres of diesel a day, how long will it be before the stbd tank is empty?

OK, ‘First Mate’ we are also having complications with the water tanks, can you read the gauges and fill in the amounts please.
We use about 100 litres of fresh water each day, how long will it be before we have to fill the fresh water tank again?
How long is this in hours?
What do you recommend we do with the ‘sewage water’ tank , you need to give me a good reason why.
The slop water has risen 150 litres what level is it at now?

I am so sorry ‘First Mate’, we have a real problem our ‘Power Supply’ display has crashed and it is so important to know we have the current power supply, can you read the gauges and fill in the amounts please?
Try to be as accurate as possible, it is very important.
