Question

A coral reef grows 0.15 m every week. how much does it grow in 13 weeks? in centimeters

Answer 1

Given:

A coral reef grows 0.15 m every week.

Coral reefs grow 13 times 0.15m for 13 weeks.

`=13*0.15m`
`=1.95\text{ m}`

We need to convert m into cm.

`1m=100cm`

Multiply 1.95m by 100, we get

`1.95*100=195cm`

Hence a coral reef grows 195cm in 13 weeks.
