    ........d

    v = ---- ⇒ vt = d

    ........t

    ......................d

    ...........⇒ t = -----

    ......................v

    Substitute d = 10 and v 2.5

    ......................10

    ...........⇒ t = ------

    ......................2.5

    ...........⇒ t = 4..................ANS

    You are given an equation:

    v = d/t

    You are given two unknowns:

    d = 10

    v = 2.5

    Substitute what you know and solve for the unknown:

    2.5 = 10/t

    Multiply both sides by t:

    2.5t = 10

    Divide both sides by 2.5:

    t = 10/2.5

    Simplify:

    t = 100/25

    t = 4
