Answer: 13 hours
Explanation:
To find out how long it would take Tammy to drive 715 miles at the same rate, we can set up a proportion using the distances and times.
The proportion would be:
605 miles / 11 hours = 715 miles / x hours
To solve for x, we can cross-multiply and then divide:
605x = 715 * 11
x = (715 * 11) / 605
x ≈ 13 hours
So, it would take Tammy approximately 13 hours to drive 715 miles at the same rate.
