    6 litres fuel being used for = 1 hour

    so, 1 litre fuel being used for = \frac{1}{6} hour

    so, 9 litres fuel being used for = \frac{1}{6} \times 9 hour

    = \frac{9}{6} hour = \frac{3}{2} hour = 90 minutes

    Hereís 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 thatís 1.5 hours, 1 hour is 60 mintues, half an hour is thirty, so 60 +30 is 90 mins.
