Question

bernard typically runs x km/hour. while he was sick, he only ran 41.5 km/hour. what equation represents that the difference in his speeds is 13.5 km/hour?
41.5 + x = 13.5
13.5 - x = 41.5
x - 41.5 = 13.5
13.5 - 41.5 = x

Explanation:

Step1: Analyze the problem

We need to find the equation that represents the difference in Bernard's speeds. The normal speed is \(x\) km/hour and the speed when sick is \(41.5\) km/hour, and the difference is \(13.5\) km/hour.

Step2: Formulate the equation

The difference between the normal speed (\(x\)) and the sick - speed (\(41.5\)) is \(13.5\). So the equation is \(x - 41.5=13.5\)

Answer:

\(x - 41.5 = 13.5\)
