A logic puzzle to finish off the holidays:
Four electric cars need to be moved 32km from A to B
The speeds of the cars are as follows:
Tesla 80m/s, Mirai 40m/s, e-Golf 20m/s, Leaf 10m/s
There is only one battery pack available which is interchangeable between all cars, and one tow rope. When a car is towed, the slowest of the two cars has to do the towing.
What is the smallest time needed to get all 4 cars from A to B (ignore accel/decel and the time taken to change battery packs and tow rope)
Answer by pm.
