Given the statement:
Erika can walk 1/4 of a mile in 2/3 of an hour.
Determine how many miles can Erika walk in 1 hour.
Solution:
Change first the fractions into decimals in order to compute the given easily.
¼ = 0.25 mile
⅔ hour = 40 mintues
Since we know that at 40 minutes, erika can walk 0.25 miles, then to find for the distance walk in 1 hour we simply need to divide 0.25 by 2, since that will be the distance walked in 20 minutes, and then add the quotient to 0.25 so we will have 60 minutes in total.
= 0.25/2
= 0.125
=0.125 + 0.25
=0.375 miles
Final answer:
Erika can walk 0.375 miles in 1 hour.
