Question

Hey can someone help, im having trouble converting alot.

IP The weight of your 1440 kg car is supported equally by its four tires, each inflated to a gauge pressure of 30.0 lb/in^2.

What is the area of contact each tire makes with the road?

What gauge pressure is required to give an area of contact of 122 for each tire?
bobpursley
4*gauge pressure*area=weight of car
4*30lb/in^2=1440kg*1lb/.454kg

check my thinking
so if the answer wants cm^2 what would be the conversion?
