Question

Mr. Blair and Ms. Stevenson are teaching their classes how to write in cursive. Mr. Blair has already taught his class 4 letters. The students in Ms. Stevenson's class, who started the unit later, currently know how to write 2 letters. Mr. Blair plans to teach his class 1 new letter per week, and Ms. Stevenson intends to cover 2. new letters per week. Eventually, the students in both classes will know how to write the same number of letters. How long will that take?

Answer 1

2 weeks

Explanation:

The next week Mr Blair’s class will have written 5 letters because his class wrote one more letter, while Ms Stevenson’s class will have written 4 letters because her class wrote 2 more letters. This next week Mr Blair’s class will write another letter leaving them at 6 letters, and Ms Stevenson’s class will write 2 more letters leaving them at 6 letters also. So all in all, in 2 weeks, the two classes will be at equal amounts and caught up to each other.
