#### Answer

a.) 29.33 hr
b.) 1.22 days

#### Work Step by Step

Given, A snail moves at a speed of 2 feet every 3 minutes.
To find how long it would take the snail to travel one mile, , First we need to find the how many seconds it will take to travel one mile.
As we know 1 mile = 5280 feet, so divide 5280 with 3.
5280/3 = 1760 minute
Now we need to convert 1760 minute to hour, you are converting from a smaller unit to a larger unit (a minute is smaller than an hour) so divide.
Because 1 hr = 60 minute, divide by 60
1760/60 = 88/3 = 29.33 hr = 291/3 hr
Therefore snail will take 29.33 hr to travel one mile.
b.) We need to calculate the time in days i.e. 1760 min= days
Use the unit fraction (1 hr)/(60 kin) to change minute to hours and the unit fraction (1 days )/(24 hours ) to change hours to days. Notice how all the units divide out except days, which is the unit you want in the answer.
1760 min * (1 hr)/(60 min) * (1 days )/(24 hours ) = 11/9 days = 1.22 days
Therefore snail will take 1.22 days to travel one mile.
