Darren has 16 motorbikes with a tank that has a capacity to go 100 miles (when the tank is full).

→ All the motorbikes are initially fully fueled.
→ Each start from the same point.
→ Each bike has a rider on it.

Using these 16 motorbikes optimally, determine the maximum distance that Darren can travel.

Note:
It is not necessary for all the bikers to reach at that final point.
