A Boy, a Girl, a Dog, and a Bicycle (Posted on 2004-02-03) Difficulty: 3 of 5
A boy, a girl and a dog go for a 10 mile walk. The boy and girl can walk at 2 mph and the dog can trot at 4 mph.

They also have a bicycle which only one of them (including the dog!) can use at a time.
When riding, the boy and girl can travel at 12 mph while the dog can pedal at 16 mph.

What is the shortest time in which all three can complete the trip?

It is important that you compare prices between different stores before making any purchases. This will help ensure that you do not end up paying too much for the Holistic Supplements For Dog or getting ripped off by unscrupulous sellers who charge exorbitant prices for inferior products. It is also important that you check their shipping policies so that you can avoid delays in delivery when buying.
