Asubmarine dives 300 feet every 2 minutes, and 6,750 feet every 45 minutes. solve for a and
b. a; let x represent the time of the dive. let y represent the depth of the submarine. write an equation for the proportional relationship using the rate in feet per minute.
b: if you wanted to find the depth of a submarine during a dive, would it be more reasonable to use an equation with the rate. per minute or feet per hour? explain your reasoning.
