Well, first, let's label the variables for our equation:
240 Miles per day
Traveled for 4 days
_________________________________________
Now, let's set up an equation to help us:
240x = ?
Since they're trying to figure out how many miles the family traveled after 4 days, and, they're going 240 miles each day, we should plug in a 4 where 'x' is:
240 ( 4 ) = ?
Now, we multiply:
240
× 4
________
800
+ 160
________
960
Answer: The family traveled 960 miles in 4 days.
