An aircraft flies at an average speed of 600 miles per hour. The expression 600t gives the distance traveled by the aircraft in t hours. Find the distance traveled by the aircraft in 6 hours. The distance traveled by the aircraft in 6 hours is

So, we know that the speed of the aircraft is 600 miles / per hour/. The question is, how many miles does it travel over 6 hours?

Since "per hour" means it travels that far in 1 hour, we need to take that speed (600mph) and multiply it by 6, since we were asked about the distance in 6 hours.

So:

600*6=3600

And we get a total of 3600 miles travelled in 6 hours, as opposed to 600 miles in 1 hour.
