A person who weighs 625N is riding a 98N mountian bike. Suppose the entire weight of the rider and bike is supported equally by the two tires. if the gauge pressure in each tire is the 7.60 X 10^5 Pa (N/m^2), what is the area of contact between each tire and the ground?

Using the pressure formula:
The pressure P excerted by a fluid is the magnitude F of the force acting perpendicular to a surface embeddedin the fluid divided by the area A over which the force acts:
p=F/A
The SI unit for measuring p.ressure is the pascal (Pa); 1 Pa= 1 N/m^2.
One atmosphere of pressure is 1.013 X 10^5 Pa or 14.7 lb/in^2

This question practically answers itself. Divide the total weight (person & bike) by 2; divide the result of that by the pressure to get contact area in m^2.
