A doubt
You travel 12 miles. How much fuel will you need if you burn 150 kgs per hour, and are travelling at 90 mph?
I have a big doubt: my reasoning is the following:
Travelling at 60mph--> 12min for 12 miles
Travelling at 120mph--> 6 min for 12 miles
Yet, if I travelled at 90mph--> 9 min for 12 miles, shouldnt that be right?????, proportional calculations.
Well no, the solution is 20, which is 0,1333 (8minutes) X 150 and not 0,15 (9minutes).
Why is this???
