Question

A coral reef grow 0.18 m every week. How much does it grow in 15 weeks? Write answer in centimeters.

Answer 1

A coral reef grows 0.18 m every week.

This means that in 15 weeks it grows:

15 * 0.18 = 2.7 m

There are 100 cm in one meter, thus:

2.7 m = 2.7 × 100 = 270 cm

The coral reef grows 270 cm in 15 weeks
