A research ship lowers a probe into the ocean to explore an underwater trench. The probe starts on a crane 17 feet above the surface and is lowered at a rate of 10.4 feet per minute. Write an expression for the depth of the probe after m minutes. What is the depth of the probe after 60 minutes?
+128731 I'm using the convention that the water surface lies at "0"...thus, above the surface is "positive" and below the surface is "negative"...so we have
d = 17 - 10.4m where d is the depth after m minutes
The depth after 60 minutes is
17 - 10.4(60) = -607 = 607 ft below the surface
