It is easier to solve problems like these by first taking the unit rate. In this case, we look for how many miles can the bird fly per hour. This is done by dividing the total distance by the total time.
Rate = 494 miles / 13 hours
Rate = 38 miles / hour
Multiplying this by 5 hours:
38 miles / hour * (5 hours) = 190
Therefore, the migrating bird flies 190 miles in 5 hours.
