A diver descends at a rate of 8 m/min. Which expression CANNOT be used to find her depth after 5 minutes?(1 point)
The expression 8 ร 5 cannot be used to find her depth after 5 minutes.
To find the diver's depth after 5 minutes, we can multiply the rate of descent by the number of minutes. So, the expression that CANNOT be used is the one that does not correctly represent this calculation.
Let's analyze the given options:
Option 1: 8 m/min * 5 min = 40 m
Option 2: 8 m/min + 5 min = 13 min
Option 3: 8 m/min x 5 min = 40 min
Option 4: 8 m/min - 5 min = 3 min
From the given options, the expression that CANNOT be used to find the diver's depth after 5 minutes is:
Option 3: 8 m/min x 5 min = 40 min
This option incorrectly multiplies the rate of descent by the number of minutes instead of multiplying the rate by the number of minutes.
