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.
Manufacturers need to minimise the amount of material used to make their product. What is the best cross-section for a gutter?
