Question

The table below shows the number of cameras made when an assembly line runs at a constant rate for a certain number of hours. Number of Hours Number of Cameras 0 0 10 300 20 600 When the assembly line runs at the same rate for 24 hours, how many cameras are made?

Answer 1

Computing the rate we get:

$\frac{300}{10}\frac{cameras}{\text{hour}}=30\frac{cameras}{\text{hour}}$

Then, when the assembly line runs at the same rate for 24 hours they will produce:

$24\text{hour}\cdot30\frac{cameras}{\text{hour}}=720\text{ cameras}$

Answer: Option C) 720.
