Hi I have a problem that is sending me grey. I know the answer is probably staring me in the face but I am going nuts to work it out here goes:
Jane,Ali and Pat each plant a tree 90cm in height.
In the time it took Janes tree to grow 1cm, Ali's tree grew 2cm. In the time it took Ali's tree to grow 1 cm, Pats tree grew 3 cm.
How tall was janes tree when pats tree was 108 cm in height.

:?

Pats tree grew 3 cm ? Ali's tree to grow 1 cm ? Janes tree to grow (1/2) cm .......................................(1)

Growing from 90 to 108 cm ? how many centimeters did Pat's tree grow?

Then use (1) to find how much did Jane's tree grow.....
