You can put this solution on YOUR website! Della is at a point three miles from her home.
She starts riding her bike 1/4 mile per minute toward home.
How long will it take her to be half a mile from home?
How long will it take her to get home?
:
Find how long it take her to get home, from the information, we know it takes 4 min to ride 1 mile, therefore:
3 * 4 = 12 minutes for the trip
:
We know that it takes her 2 min to ride 1/2 mi, therefore:
12 - 2 = 10 min, to be a 1/2 mi from home
