Answer
11 hours to travel 5390 miles
Work Step by Step
The plane is flying at a constant rate of 490 miles per hour and we have to find how long it would take it to travel 5390 miles. The equation would be 490h=5390.H represents the number of hours.
490h=5390 -divide both sides by 490-
h=11
It would take the plane 11 hours to travel 5390 miles.
