Question

The smith family took three days to drive to Florida. They drove m miles on the first day. On the second day, they drive five more miles than they did on the first day. If they drove three times as many miles on the third day as they did on the second day, write an expression to represent the total miles they drove in simplest form.

Answer 1

Answer: 5m + 20 miles

Explanation:

Miles driven on first day = m

On the second day, they drive five more miles than they did on the first day. This will be: = m + 5

On the third day, they drove three times as many miles as they did on the second day. This will be:

= 3(m + 5)

= 3m + 15

Total miles driven will now be:

= m + m+5 + 3m + 15

= 5m + 20
