    Answer:

    5.92×10⁷ J

    Explanation:

    We’ll begin by converting 15 tons to Newton. This can be obtained as follow:

    1 ton = 9806.65 N

    Therefore,

    15 ton = 15 ton × 9806.65 N / 1 ton

    15 ton = 147099.75 N

    Next, we shall convert one-quarter (¼) or 0.25 mile to metre. This can be obtained as follow:

    100 mi = 160934 m

    0.25 mi = 0.25 mi × 160934 / 100 mi

    0.25 mi = 402.335 m

    Finally, we shall determine the Workdone. This can be obtained as follow:

    Force (F) = 147099.75 N

    Distance (d) = 402.335 m

    Workdone (Wd) =?

    Wd = F × d

    Wd = 147099.75 × 402.335

    Wd = 5.92×10⁷ J

    Thus, the Workdone is 5.92×10⁷ J
