What is the linear velocity in miles per hour of the tip of a lawnmower blade spinning at 2600 revolutions per minute in a lawnmower that cuts a path that is 24 inches wide?

In 1 revolution the blade tip travels (22 x pi) = 69.124", divide that by 12 then multiply by 2300 = 13,248.77 ft/min. (5280/60) 88ft/min. per 1 mile. (13,248.77/88) = 150.55mph.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
