Victoria's family had traveled 680 miles when she fell asleep on their road trip to Mount Rushmore, calculated by multiplying 1000 miles by 68%.
To determine the distance traveled when Victoria fell asleep, you can find 68% of the total trip distance. If the total length of the trip is 1000 miles, you calculate this by multiplying 1000 by 0.68:
Therefore, Victoria's family had traveled 680 miles when she fell asleep.
In summary, to find the distance traveled when Victoria fell asleep, multiply the total trip distance (1000 miles) by the percentage of the trip she slept through (68%). The result is 680 miles.
