Question

If snow is falling at a rate of 1/4 inch every 30 minutes, how much snow will fall in 4 1/2 hours.

Answer 1

The answer is 2 1/4 inch or 2.25 inch per 4 1/2 hours

Answer 2

`30min=0.5h\\\\(1)/(4)inch=0.25inch\\\\4(1)/(2)h=4.5h`



`0.25inch\ -\ 0.5h\\\\2\cdot0.25inch\ -\ 2\cdot0.5h\to0.5inch\ -\ 1h\\\\\\0.5inch\ -\ 1h\\0.5inch\ -\ 1h\\0.5inch\ -\ 1h\\0.5inch\ -\ 1h\\0.25inch\ -0.5h\\------------+\\2.25inch\ -\ 4.5h`
