To calculate the energy burned while running, we use the formula: Energy burned = weight x distance x 1.036. In this case, the weight of the person is 75 kg and the distance run is 3,200 meters. The constant 1.036 represents the energy expenditure per kilogram per meter. By substituting the values into the formula, we get: Energy burned = 75 kg x 3,200 m x 1.036 = 246,240 joules. This means that the person burned 246,240 joules of energy during the run.
