Question

A glacier in Republica was observed to advance 22inches in a 15 minute period. At that rate, how many feet will the glacier advance in one year?

Answer 1

To fins the rate in feet/year we must change first the measurements to the units required

inches to feat

minutes to years

`22in\cdot(1ft)/(12in)=(11)/(6)ft`
`15\min \cdot(1h)/(60\min)\cdot(1day)/(24h)\cdot\frac{1year}{365\text{days}}=(1)/(35040)\text{years}`

to find the rate divide the distance over the time

`\frac{(11)/(6)ft}{(1)/(35040)\text{year}}=\frac{11\cdot35040ft}{6\text{year}}=(385440)/(6)=\frac{64240ft}{\text{year}}`
