Answer:

  2.1 tons

Step-by-step explanation:

Use the given values in the formula and do the arithmetic. The area will be the product of the contact patch dimensions:

  A = (7 in)(5 in) = 35 in²

So, the weight is ...

  W = (35 in²)(30 #/in²)(4)/(2000 #/ton) = (4200 #)/(2000 #/ton)

  W = 2.1 tons

The car weighs about 2.1 tons.

Solving this involves substitution of values into the given formula and applying basic arithmetic.

Weight of Car is 2.1 tons

We are told that the dimensions of the rectangle are 7in and 5in.

Formula for area of a rectangle is;

A = Length x breadth

Thus;

A = 7 × 5

A = 35 in²

We are also given;

Air pressure; P = 30 psi

A car has 4 tires and so;

Number of tire; N = 4

We are told that formula for weight of the car in ton is;

W = APN/2000

Plugging in the relevant values;

W = (35 × 30 × 4)/2000

W = 2.1 tons
