In the context of the function \( y = 80x + 2 \), where \( y \) represents the speed measured in miles per hour and \( x \) represents the time in hours of the road trip (including the stops), the quantity that describes the x-axis is:

time in hours

so what's the answer

The answer is:

time in hours
