6 litres fuel being used for = 1 hour
so, 1 litre fuel being used for $\displaystyle = \frac{1}{6}$ hour
so, 9 litres fuel being used for $\displaystyle = \frac{1}{6} \times 9$ hour
$\displaystyle = \frac{9}{6}$ hour $\displaystyle = \frac{3}{2}$ hour = 90 minutes
Here’s how I see it:
Look at it this way, you have 9 litres of fuel to burn. And you can burn 6 litres in 1 hour. That leaves 3 litres left after one hour of riding. And because you know that in 1 hour, you burn 6 litres, 3 is half of one hour. So you already had one hour of riding, plus another half hour, so that’s 1.5 hours, 1 hour is 60 mintues, half an hour is thirty, so 60 +30 is 90 mins.
