for a car moving at a constant speed,the distance traveled varies directly with the time spent driving in such a car travels 390 miles in 6 hours how long does it take to travel 585 miles?
To solve this problem, we can set up a proportion:
390 miles / 6 hours = 585 miles / x hours
Cross multiplying, we get:
390x = 3510
Dividing by 390 on both sides, we get:
x = 9
Therefore, it will take 9 hours to travel 585 miles at a constant speed.
