A word problem is used to solve problems in mathematics without the explicit use of equations initially.
<h3>What is a Word Problem?</h3>
This refers to the use of words to generate an equation that can be solved by mathematical means.
Hence, we can see that because the question is incomplete, we can infer that there is a relationship that exists between Dr. White, Dr. Black, Dr. Brown, and a woman that does not have brown hair, and equality would be used to solve it.

Answer:
160 cars
Step-by-step explanation:
The computation of the number of more cars he washed this year is given below;
Last year, he washed 20 cars a week so on yearly basis he washed
= 20 cars × 52 weeks
= 1,040 cars
And, this year he washed 1,200 cars
So, the number of more cars he washed this year is
= 1,200 cars - 1,040 cars
= 160 cars
3 meters = 300 cm
300 cm = 3000 mm
