Question

A submarine 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.

Answer 1

A; X = 60, Y = 150. I found the answers by dividing 300 into 2, and 6,750 into 45. 

B; It's better to do per minute, since there's no need to divide back to find the original time.
