Answer:

Rachel is 36.5 years old

Sarah is 30.5 years old

Explanation:

Their ages add to 67, so 67 divided by 2 is 33.5 (each)

Rachel is 3 years older than Sarah, so to add 3 years old for Rachel and minus 3 years old for Sarah.

Rachel is 33.5 years old + 3 years old = 36.5 years old

Sarah is 33.5 years old - 3 years old = 30.5 years old
