To solve this problem, we can use the unit rate of miles per hour that Dante drove.
The unit rate of miles per hour is:
871 miles ÷ 13 hours = 67 miles per hour
This means that Dante drove at a rate of 67 miles per hour.
To find out how long it would take him to drive 603 miles at the same rate, we can set up a proportion:
871 miles ÷ 13 hours = 603 miles ÷ x hours
We can cross-multiply to solve for x:
871x = 13 * 603
871x = 7,839
x = 9
Therefore, it would take Dante 9 hours to drive 603 miles at the same rate of 67 miles per hour.
