Question

Rohan, Amber, and Sahara were discussing the following problem. A submersible dives from the surface at 15 m/min for 6 min and then at 25 m/min for 20 min. What is the depth of the submersible after the dive? They worked together to write the following expression to solve the problem. 6 × (-15) + 20 × (-25) Then they evaluated the expression independently. Rohan evaluated the expression as +1750. Amber evaluated the expression as -590. Sahara evaluated the expression as -750

Explain how the expression represents the problem.
