The magnitude of the vector cross product is the desired area.
║A×B║=║A║·║B║·sin(α) . . . . . where α is the angle between the vectors.
As it happens, this is also the formula for the area of the parallelogram defined by vectors A and B.
328 ÷ 4 = 82 mph. (unit rate)
82 x 10 = 820.
Haley can drive 820 miles in 10 hours, and drove 82 miles per hour.
hopefully this helps
