If a person walks with a speed of 1.1 mi/h, it takes 90 min. to walk around the rim. Assuming that the rim is a circle, what is the diameter of the crater?

Question

Consider another volcanic crater similar to the Ubehebe Crater in Death Valley.

Answer 1

90 min = 1.5 hr.

1.5 hr * 1.1 mi/hr = 1.65 mi.
