Question

The Pacific Giant Kelp grows at a rate of 18 in/day. How many centimeters per hour is this?

Answer 1

For this case we must do a conversion. By definition we have to:

1 inch equals 2.54 centimeters

1 day equals 24 hours.

So, we have:$18 \frac {in} {day} * \frac {1} {24} \frac {day} {h} * \frac {2.54} {1} \frac {cm} {in} =$

Canceling units we have:

$\frac {18 * 1 * 2.54} {24 * 1} \frac {cm} {h} =\\\frac {45.72} {24}\frac {cm} {h} =$

$1,905 \frac {cm} {h}$

Answer:

$1,905 \frac {cm} {h}$
