1. We are given a mixture with a mass of 100kg that consists of 50% Aluminum (Al, 100% purity) and 50% Iron (Fe, 100% purity) and we want to produce a final mixture with a mass of 150kg that consists of 75% Aluminum and 25% Iron by adding mass “x” of Aluminum and removing mass “y” of Iron. Calculate the ratio of x/y.

No part of the vehicle may enter a keep-out-zone defined by two lines extending vertically from positions 75 mm in front of and 75 mm behind the outer diameter of the front and rear tires in the side view of the vehicle, with steering straight ahead. This keep-out zone extends laterally from the outside plane of the wheel/tire to the inboard plane of the wheel/tire assembly.

B. The minimum static ground clearance of any portion of the vehicle, other than the tires, including a driver, must be 25 mm.

C. The vehicle must have a wheelbase of at least 1535 mm.
