There is construction on the roads B - N which prevent any cars from crossing. Using any combination you wish without using the same means twice, what is the fastest time it would take you to travel from H to A and then to O?;
CAR = 2 MIN
BIKE = 2 MIN 20 SEC
FOOT = 3 MIN 20 SEC
I keep getting 20 min 20 sec? The actual answer is 20 min flat? Am I wrong???
Any help appreciated
