Suppose there is a second station with raw material for the robot at the other extreme of the line which is 60 metres from the origin, that is, 10 metres from E. After finishing the services in a trip, the robot returns to the nearest station. If both stations are equidistant, it chooses the origin as the station to return to. Assuming that both stations receive the messages sent by the machines and that all the other data remains the same, what would be the answer to the above question?

Solution

The correct option is A 120
In this question, once the robot has delivered the material to machines A and D, it shall reach the origin 2 (nearest), taking 6s and covering 60 m. Then it immediately moves to deliver material to machines C and B covering a distance of 40 m and finally back to the origin (nearest). Thus, it covers a distance of 60 m. Hence, it covers a total distance of 120 m.
