Question 26
A courier company has motorbikes which can travel 300 km on a full tank of fuel. Two couriers, Anna and Brian, set off from the depot together to deliver a letter to Connor’s house. They can transfer fuel between the bikes at any time but do not return to the depot to get more fuel. While only one bike is required to deliver the letter, both must return to the depot. What is the greatest distance, in kilometres, that Connor’s house could be from the depot?
