1. Suraj took a slice of pizza from the freezer and put it in the oven. The pizza was heated at a constant rate.
The table compares the pizza's temperature (in degrees Celsius) and the time since Suraj started heating it (in minutes).
Time (minutes) | Temperature (degrees Celsius) |
---|---|
\(1\) | \(2.5\) |
\(7\) | \(47.5\) |
\(13\) | \(95.5\) |
How fast was the pizza heated?
