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.
