A driver’s distance varies directly as the amount of time traveled. After 6 hours, a driver had traveled 390 miles. How far had the driver traveled after 4 hours?

260

Step-by-step explanation:

you would divide 390 by 6 to see how many hours were  per hour, which is 65. You would then multiply it by 4 to see how far they drove in 4 hours, and you get 260. To prove this is right for sure you could multiply 65x2 which is 130 and add 130+260 which would make up the 6 hours and you’d get 390
