Geology question?

Say that the present-day diameter of Manicouagan Crater is 75 km and the present-day diameter of Meteor Crater is 1.2 km. Assume that a 40-m-diameter meteorite created Meteor Crater. Although clearly an oversimplification, use a simple ratio between meteorite size and crater diameter to estimate the size of the meteorite that might have created Manicouagan Crater (use the crater diameters I provided).

Choose one:

 ~40 m

 ~170 m

 ~2,500 m

 ~3,500 m

    The ratio is

    75 km / 1.2 km = a / 40 m

    75 X 40 = 1.12 a

    3000 / 1.12 = a

    2678.57 = a

    2500 m is the best answer.
