a turtle was crawling at the rate of 43 cm per minute.how many kilometers would this turtle crawl in one dsy?(24 hours) if it did not rest and continued to craw

Question

please help me I am so confused.

Answer 1

This is dimensional analysis.  Here's how:  A x B/A x C/B  Units must match!

 

Begin with the given: 43cm/minute

 

Write next conversion factor putting cm on the bottom so it will cancel out.

 

43cm/min x 1m/100 cm

 

repeat, going from m to km

 

43cm/min x 1m/100 cm x 1km/1000m

 

Now, work on time the same way:

 

43cm/min x 1m/100 cm x 1km/1000m x 60 min/1 hr x 24 hr/ day = .62 km/day
