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?
x – 41.5 = 13.5
41.5 + x = 13.5
13.5 – x = 41.5
13.5 – 41.5 = x

Answer 1

The answer is
`x-41.5=13.5`

Explanation:

To find the correct equation we have to separate each one of the terms:

Typically runs = x km/hour

Sick run = 41.5 km/hour

Difference in speed = 13.5 km/hour

This is a case of a subtract, so we have to subtract the typically run and the sick run and the answer will be the difference in speed, this is=

`Typically-Sick=Difference`

In the terms of the answers, we have:

`x-41.5=13.5`

The answer is
`x-41.5=13.5`

Answer 2

Typical speed of Bernard= x km/hr
Bernard's speed while sick= 41.5 km/hr
the difference in the speed=13.5 km/hr
the equation representing the difference will be:
x-41.5=13.5 km/hr
