A submarine dives 300 feet every 2 minutes,and 6,750 feet every 45 minutes

Question

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 per minute

Answer 1

The rate of descent is 150 feet per minute

y = -150x + 0 <--- surface of the water at zer0 feet

= -150x
