Question

Juliette buys a rosemary plant that is 12 cm and grows 1 cm per

week (w). Kimberly starts one from seed but the package says it
will grow
2 cm per week. How many weeks will it take for
Kimberly's plant to equal the height of Juliette's?

Answer 1

The growing progress can be tracked like so:

Juliette: 12: 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24.

Kimberly: 0: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24.

All you have to do now is count how many numbers are in each column.

It will take 12 weeks for Kimberly's plant to be the size of Juliette'e.
