Answer: 8.76 hours
Explanation: The speed of the crab is s = 5km/year
And we want to know how long will take the crab to crawl 1 meter.
First, the speed equation is written in kilometers, and the distance is in metters, so we need to convert the equations:
We know that 1km = 1000m
So the speed equation can be s = 5km/year = 5*1000m/year = 5000m/y
So the crawl moves 5000 meters in one year.
the time that the crab needs to crawl 5 meters is:
t = (5 m)/(5000m/year) = (1/1000)years
now, a year has 365 days:
t = (365/1000) days
each day has 24 hours:
t = ((365*24)/1000) = 8.76 hours
The crab needs 8.76 hours to crawl 5 meters
