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?

Answer:x - 41.5 = 13.5Step-by-step explanation:Bernard typically runs x km/hour. While he was sick, he only ran 41.5 km/hour. If we consider that Bernard typically runs faster than what he ran while he was sick. Then the equation that represents that the difference in his speed is 13.5 km/hour is  x - 41.5 = 13.5 ........ (1) (Answer) Solving this equation we get x = 55 km/hour. So, Barnard typically runs 55 km/hour.
