    Expressions

    If you could help it would be appreciated!!!
    #1 I need to show an algebraic expression to show, "The distance (in miles) traveled in h hours at an average speed of 55 mph?"


    #2 The quotient of two consecutive integers, the smallest being n.


    #3 The perimeter of a rectangle whose width is half its length L
    I think it is P= L* (1/2L)

    Distance = Speed x Time

    Distance (in miles) = 55 x h


    #2 The quotient of two consecutive integers, the smallest being n.

    Smallest = n, the next consecutive number is n + 1 and the quotient of the two consecutive integers would be expressed as:

    \frac{n + 1}{n}

    #3 The perimeter of a rectangle whose width is half its length L
    I think it is P= L* (1/2L)

    Length = L
    Width = half its length = 0.5 L (or 1/2 L)

    Perimeter = (Length + Width) x 2... that is, (L + 0.5L)x2 = 3L
