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:[tex]18 \frac {in} {day} * \frac {1} {24} \frac {day} {h} * \frac {2.54} {1} \frac {cm} {in} =[/tex]
Canceling units we have:
[tex]\frac {18 * 1 * 2.54} {24 * 1} \frac {cm} {h} =\\\frac {45.72} {24}\frac {cm} {h} =[/tex]
[tex]1,905 \frac {cm} {h}[/tex]
Answer:
[tex]1,905 \frac {cm} {h}[/tex]
