It's going to run out before it reaches its destination.
There are ten people on the bus at the moment, and it can travel five miles on one litre of fuel.
For each person that gets off the bus, it can travel one mile farther.
If all of the people get off the bus, and two litres of fuel has been added, how many more miles can the bus travel?
Let's go over the facts.
Everbody has got off the bus so that it can travel farther, and the bus has five litres of fuel remaining.
How many more miles is it able to travel?
The bus has been made lighter and more fuel has been put in.
Now it just needs to get moving, but has something been overlooked?
Everyone has got off, so there is nobody left on the bus.
There's nobody on the bus to drive it.
It can't go anywhere like this.
