Question

A conveyor belt moves at a constant rate of 12 feet in 3 seconds. A second conveyor belt moves at a constant rate of 21 in 7 seconds. Does this situation represent a proportional relationship? (1-2 Understand Proportional Relationships)

1. Yes
2. No

Answer 1

The situation does not represent a proportional relationship.

Step-by-step explanation:

To determine if the situation represents a proportional relationship, we can compare the rates of the two conveyor belts. The rate of the first conveyor belt is 12 feet in 3 seconds, which can be simplified to 4 feet per second. The rate of the second conveyor belt is 21 feet in 7 seconds, which can be simplified to 3 feet per second.

Since the rates of the two conveyor belts are not equal, the situation does not represent a proportional relationship. Therefore, the answer is 2. No.
