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

4 is 2/3 of 6, so he traveled
2/3 of 390 = 260 miles

you can use a simple proportion
6/390 = 4/x
6x = 1560
x = 260
it looks like he is traveling at 65 mph
so in 4 hours he would go 260 miles
