Final answer:
Clare skated 3/5 farther than Mai, so you add 3/5 of Mai's distance, x, to her original distance, giving you x + 3/5x, which corresponds to option B among the given choices.
Step-by-step explanation:
The question asks for an expression representing the distance Clare skated, given that she skated 3/5 farther than Mai, who skated x miles.
To find the total distance Clare skated, we want to add the additional distance to Mai's distance.
The additional distance is 3/5 of Mai's distance, which is (3/5)x.
Therefore, the total distance is Mai's distance x plus the additional distance (3/5)x, resulting in the expression x + (3/5)x, which simplifies to x + 3/5x.
Among the given options, option B represents the correct expression for the distance Clare skated.
