In Nutrition and Cycling, you were invited to work out Andy's calorie needs on a ride from Land's End to John o'Groats.
If you haven't already done so, print out a copy of these cards.
Andy is competing in a Land's End to John o'Groats race, and YOU are his coach!
You are determined that Andy will win the race, as long as he is willing to cycle for more than 7 hours a day.
What is the shortest time in which Andy could complete the ride, if we ignore his 7 hour daily cycling limit, while making sure his energy needs are met?
You may wish to consider minimising the cost, and/or the weight that Andy needs to carry, together with any other appropriate constraints that occur to you.
