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?
O x-41.5=13.5
O 415+x= 13.5
O 13.5-x=41.5
O 13.5-41.5=x

Answer 1

So we know that he usually ran x km per hour. Now he is running 41.5 km per hour and the difference is 13.5 so it would be x-41.5=13.5
