Hello There! The answer is 455 miles.
To solve this problem, you want to find the unit rate of how far a car goes per hour. To do this, divide the number of miles given by the number of hours given.
280/4 = 70 miles per hour.
Next, take the unit rate and multiply it by the number of hours you are trying to find. In this case, you are trying to find 6 hours and 30 minutes, but this can also be rewritten as 6.5, since 30 minutes is half an hour.
70 x 6.5 = 455
So, in 6.5 hours, the car can go 455 miles.
